Tom's MythTV Saga

I am installing a MythTV front-end / back-end combination. I figured that it would be an ordeal, so I decided to blog the process. It is currently working, but in a duct-tape-and-band-aids sort of way.

Resolution upgrade

I've been running 960x540p for a long time.  It is a nice resolution, but HDTV is true 1920x1080i resolution.

So, I decided to try it again (failed previously).  I decide to pull out the big guns and use Powerstrip to find the right settings.  I must say that Powerstrip rocks.  I followed Mark Rejhon' excellent guide to detect the right modes on Windows (brought another box down) and it even gives you the XF86 Modelines for what you're doing.

So, I copied all the modelines over to my front-end... and it didn't work.  This is what I got:

It's supposed to look like this...

After hours and various incarnations of configuration, including using the exact same card in my Windows 2000 box, I still had no progress.  Until now.  I just found a post that says that this is a known issue with "newer versions" of nVidia drivers and only happens in 1080i modes.  That makes me want to kill somebody :)

So, now I'm going to try downgrading my drivers and see if I can find one that won't exhibit this issue.

Update: I downgraded to 1.0.6629 and it works like a charm.  I had to go back to Windows one more time to tweak, but it's working now.  SWEET!

Update 2: Well, trying to change video modes to "Zoom", which is trying to take a 4:3 recording with a 16:9 letterboxed image to full screen, the bottom 1/6 or so of the screen flickers too much to watch.  This is annoying

Update 3: Here's my XF86Config file
