Hi, Just upgraded to R5E50. Everything went well but I am now having problem with stutter while watching live tv and trying to change channels.

I have a P3 1ghz 512meg ram with divco Plus with 20gig hd.(combined frontend/backend)

I had no worries watching sd tv on R5D1 was always smooth. But now when i change channels and the osd comes up its very stuttery nearly to the point of crashing. Once the OSD fades then im fine and dandy.

I did a auto upgrade.

Does anyone have any ideas. Does the new version need a faster computer to run on a combined frontend/backend.

I noticed that the E is a lot slower than the D.
Currently I am running it using an EPIA 10000 (=1Ghz) and playback and menu browsing was smooth with D, but now with the E the menu browsing is a lot slower.

Also the fact that XvMC is not working, does not help when playing back.
It used to work with C, but as of D it does not offload processing power from the CPU.
It seems this is fixed in SVN now, but I do not know if I can easily upgrade this (guess not).

So, in short, for me the E release is much more CPU hungry than D.

E50 does seem significantly slower for me as well. When I installed R5D1 originally I didn't see any slowdowns with recording and playback on my 2.1GHz 512Mb RAM system. But now I can't watch live TV because it stutters so much, unless I pause for a few seconds to let it get a little bit ahead. Or is this some other problem I'm not aware of?

Either way, the new release does seem a little more hungry. And I'm torn, because I'd love to have MythArchive included and everything, but I'm not sure it's worth the lag time...

Search for recent posts on XvMC, there's a configuration file that needs to be tweeked, at least for the nvidia version of the library. I'm guessing it would apply to the Epia too.

This seems uncannily processor-intensive. When I run top I see a 99% CPU usage by mythbackend whenever it records. Or, if I'm watching something while recording, the numbers go to 70-30 for backend-frontend. I never got anywhere near that with R5D1. What's been changed to make this release so greedy?

FWIW, I had some of the same choppiness/slowness issues as well with a clean install of R5E50. It was so bad to the point of just arrowing through the menu's it took 3 or 4 seconds between icons. Watching Live or Recorded TV was worthless, whereas R5C7 had none of these issues.
I decided to update my video driver as I had recently upgraded to an Nvidia 6200 and updating the drivers on my R5C7 worked wonders. I ran:
and I was pretty much back in business. I then decided to go to the 1.0-8776 driver and it wanted me to use the -force option. This time I ran and I can now watch Live TV or Recorded shows without issue.

Hope that helps someone!
Thanks again for everything...Knoppmyth Rocks!

Possibly a known problem:

I'm seeing reasonably high CPU usage and the following:

I have an OSD induced audio and video studder when watching HD content. Hoping that a solution appears here...

I also get some subtle video studder watching DVDs with the myth player.

My box is an nvidia box running R5E50.

What version of the nvidia driver are you running?

Ummm... whatever version comes default with RE50.
How do I check? I'll look when I get home.

I've got similar problems as well. Initially I thought R5E50 was more responsive with live tv, which was true in the time it took to load the buffer and start playing, but menu and especially playback of HD content is much worse than D was for me with both Xvmc and Libmpeg2. In particular, I find that fast forward or rewind is now macroblocking and after a few seconds freezing up. Mine was an auto upgrade from previous version and I have not yet played with the Nvidia drivers, but I'm getting close.

I have found that the cleanest playback comes if I mark my position, return to the recorded programs menu, and then play the file again. It feels like the on-screen that is causing problems, how would I tell from top?

R5.5 Upgrade from F27

I did as someone else suggested and got my xvmc working by Changing the path in /etc/X11/XvMCConfig and edit it to where the xvmc is in /usr/lib.

That fixed alot of my problems and I nolonger get jambs. Still slows down when i have a osd up especially if theres loads of writting but its useable.

One strange thing is that I never normally have the hd channels loaded. They are there but i have made them invisible cause my machine was to slow. I accidently clicked on one after the upgrade and it works with out the stutter I previously had. OSD slows my machine but HD doesnt.

My setup p3 1ghz 512k ram, 20gig hd, fx5200, Dvico plus.

Digriz77,

This step you mentioned--is this the same thing tjc was referring to above?

How would we know if this is necessary?

If it does not respond with:



then you need to edit the file to include the above.

Whilst this has helped me, it hasn't completely eliminated the problem. This version of .20 seems to be much more resource hungry currently.

Has anyone found a solution to this problem yet?

Using XvMC and ChromaKey OSD on the 8776 nVidia drivers (FX5200), HDTV is silky smooth, but as soon as the OSD is used (or in LiveTV), the audio and video become stuttery. Very annoying! I mainly notice the problem on 1080i content, anything less and the problem (mostly) goes away.

Also, as soon as the OSD disappears, everything is back to normal!

Thanks!
