Post subject:  Picture fuzziness and Scheduling TIming off
Ok, I have everything working and have video and audio just fine, but I have 2 problems

Problem 1: the video is fuzzy and not sharp at all and has some little lines moving through it like it has a refresh problem or something.

Problem 2: All of my schedules are off by -5 hours, and I know it is because I didnt set the time correctly in the setup, how do I change the time settings at this point?

1. I am a linux noob and dont know how to get into a linux window to put commands in and stuff.

2. The pictures are actually BETTER at higher channels.

I'm pretty sure that the page eviltwin pointed you to contains a link to this one: http://www.knoppmythwiki.org/index.php?page=LinuxTips which contains detailed instructions on this.

Have you tried the other frequency sets? That setting is under the general tab in mythttv-setup. This page contains detailed instructions on how to get back into that - http://www.knoppmythwiki.org/index.php?page=GettingBackIntoMytTVsetup

You're not providng a lot of information to go on...

- What are you using for output?

- What is your output resolution?

- What are you using for capture?

- What are your capture parameters?

- Are you deinterlacing the output? Have you tried fiddling with the playback setup and turning on "bob" deinterlacing or the like?

1. Geforce 3 Ti200 Composite Output (RCA cable)

2. Whatever it automatically sets at? NTSC?

3. Hauppage PVR250 Cable from Cable Line

4. What are capture Parameters?

5. I have tried all options of deinterlacing and not deinterlacing at all.

Hopes this helps!

The composite output is probably at least part of your problem, and that card is old enough that I don't think you can use nvidia setting to tune up your video or fix your overscan settings either. :-(

See this wiki page of log files and check what resolution it's using in your X log. http://www.knoppmythwiki.org/index.php?page=CheckingLogFiles I found that switching to an output resolution (640x480) that better matched the capture resolution (480x480) produced far better picture quality.

BTW - Most of these pages are linked from the main TroubleShooting Page on the wiki: http://www.knoppmythwiki.org/index.php?page=TroubleShooting

OK, pretty vanilla.

Under setup look at your recording profiles. I'm guessing that you're using the default profile and it's 480x480 but double check on that.

Some of these are affected by other factors like the MPEG decoder library or whether or not you're using XvMC.
