I wouldn't go so far to call it choppy, but my recordings often just don't look smooth....like they are being played back with less of a framerate. My CPU usage usually stays around 50% and never goes above 60%, so it isn't like the CPU is maxing out. It doesn't look like my memory is going into swap either, since my swap is 0. It's weird because people's lips usually move ok, but when the camera starts panning around things look their worst. (Obviously more screen change during those moments.)
I run a 1080i modeline, so the 1080i recordings are often a bit better than the 720p (which obviously need to be deinterlaced.) My 720p recordings sometimes have garbled noise added to the recordings, but it's happening less often since I enable extra audio buffering. Sometimes stopping and restarting the recording helps, but it often doesn't help.
I turned off the captioning option. (which I read as a suggestion here.)
In my TV Playback settings, I have:
Deinterlace playback unchecked.
Preferred MPEG Decoder: Standard
Vertical sync unchecked.
Realtime Priority threads checked.
Use video as timebase unchecked.
Extra audio buffering checked.

This is a classic symptom of deinterlacing issues. Anything with horizontal motion will accentuate it... it's not the amount of screen change but the type of motion. ed3120 wrote: I run a 1080i modeline, so the 1080i recordings are often a bit better than the 720p (which obviously need to be deinterlaced.)
It's actually that the 720p needs to be _interlaced_ when you run 1080i. I know what the deinterlacing settings are but not sure what the options are for interlacing progressive material.

I am running a 1080i modeline and then in Settings -> Appearance -> Video Mode Settings
I have GUI and Video Output set to 1920x1080 and then under Overrides I set it to use:
1280x720 for 1280x720 Any Default
I just did this today and confirmed with my TV that it was switching between 1080i and 720p (for some reason I thought Lost was 1080i but myth thinks it is 720p)
I watched a little CSI Miami (Lots of fast pans) and some Lost & American Idol and everything looked good...of course the real test is to watch a few shows completely and get the WAF

Is this what you mean by "not smooth": When I see an opening scene where the camera pans across a skyline, I will sometimes see a jerkiness I call "cogging" because it looks like gears turning with a missing tooth. It pans, jerks, pans, jerks, etc.
I have seen this throughout my experience with MythTv. I am not sure what causes it. At one time I thought it was the difference between the 24 frames/sec that film uses vs. the 30 frames/sec displayed by the TV. In other words, that we need a "3:2 pulldown" feature in our playback to smooth out the cogging.
In my setup, I found I get BETTER results from DISabling the "real time" priority setting. But it doesn't cure it entirely on all programs.
If you want to know if a show is 1080i or 720p, look at the program's size in MythWeb. 1080i programs use 7-8G bytes/hour and 720p uses 4-5G bytes/hour. You can also start mythfrontend with a "verbose" option and it will tell you the resolution when you begin playing (in its log file) but that's a lot more bother.

I'm trying to set up those video settings, but the "Output" under "Overrides for specific video sizes" doesn't allow me to choose 1280x720...the closest one is 1280x720. Your Myth actually let you pick 1280x720? Could you please note down your exact config on that screen?
Two questions...I guess I would need to add a valid 1280x720 modeline to my XF86Config-4 before I could use this feature? Also, are you choosing "Any" or forcing it to 60hz. I know my TV is very happy displaying a 60hz signal, so wonder what the difference is between forcing it or not.
I'm guessing this override option, along with a 720p modeline, would allow the video to go through without any need for interlacing, thus allowing both 1080i and 720p to be sent to the TV in their native formats. Thanks for pointing this out!!
Am I right in assuming that this override would pump 720p directly to my TV.

It pans, jerks, pans, jerks, etc. I've seen video shown by an underpowered CPU, it just looks awful and keeps hiccuping. The problem I'm getting, is things just look a little off, like in the old days when computers couldn't really handle video...like how video would be only 15 fps. It wasn't so much choppy (which I would use to describe 5 fps, but it just wasn't "full motion.") That is the best way I can describe the effect I'm getting.

I could see the logic in the whole 3:2 pulldown thing, but this is network TV, which is filmed either at 30 fps or 60 fps, so it couldn't be 3:2 pulldown.

You can also start mythfrontend with a "verbose" option and it will tell you the resolution when you begin playing (in its log file) but that's a lot more bother. Another quick way to determine it is based on the channel. Fox, ABC, and ESPN always use 720p, whereas NBC, CBS, WB, PBS and just about every other cable HD channel use 1080i. The format doesn't change show per show, so if one show on the channel is 1080i, then they all are.

Ed3120,
Sorry I didn't mention that earlier, you do need a working 720p modeline.
Here are the 2 modelines I am using:
ModeLine "720p" 89.011 1280 1296 1360 1648 720 722 728 750
ModeLine "1080i" 74.25 1920 1960 2016 2200 1080 1082 1088 1125 Interlace
I chose ANY and Default for the 60hz and 16:9/4:3 options

Thanks, I got that all set up now and my TV is reporting 720p for the the 720p shows and 1080i for the 1080i shows. This looks like it'll fix the issue for the 720p shows, but I'll probably have the same symptoms for the 1080i shows (although the problem was less for 1080i).
I'll have to sit down and watch a few shows before I can verify.

I was just watching a recording and it turns out my CPU is being pinned at 100% and that is slowing down my framerate.
Top reports about 45% user and 50% or so system, and 0% idle. I can see that specifically, mythfrontend is running as mythtv and is representing the user portion, and XFree86 is running as root and representing the system portion. My load average was sitting aroun 2.0, which is obviously a bad thing.
I'm not sure where to begin troubleshooting this. I set commercial flagging to run in the middle of the night, so that isn't doing it. I'm currently having an issue where my machine believes that /dev/hda1 is 100% full. It is because my mysql.log keeps growing and I can't stop it. Even if I delete the file, my machine still reports /dev/hda1 as 100% full. I tried a
"mysqladmin flush-logs" - but that didn't help.
Is my CPU underpowered, or am I just running into a problem here that I can fix?

My main frontend is an AMD XP2500 mobile running at about 2.1ghz so I do not think CPU power is your problem.
Are you running or have you tried XVMC?
With XvMC mythfrontend uses about 30% of my CPU.
Also, the XFree86 CPU usage seems excessively high to me.
Want to post your XF86Config-4 so we can take a look?

I don't know much about DPMS and DDC. Is there any reason to keep them on? (Keep in mind I'm not using a monitor, so monitor probing probably wouldn't do any good here.)
Another different I notice between our configs, is that you don't have any vertical or horizontal syncing. I just noticed that my 1080i modeline has both vsync and hsync turned on, and my 720p has vsync turned on. I wonder if that could cause a significant increase in CPU usage.

If you are not in a rush, I would suggest disabling one thing at a time so we know what fixes it.
I believe you do not need either DPMS or DDC. I think DDC probes for modelines of your monitor/TV and you have that all set already.
And I think DPMS has to do with putting monitors into power saving mode.
Hope one of these fixes your problem.
