[mythtv-users] MSI MX440SE-T and Overscan, Best cards for NTSC TV-Out

[Roy Hooper]

I am getting pretty tired of trying to get a top quality TV-Out signal 
for NTSC+Svideo.

I've tried:
- XFree 4.2.0 + nvidia's 
http://www.nvidia.com/object/linux_display_ia32_1.0-4496.html driver
- XFree 4.2.2
- XFree 4.3.0
- I've tried making nvtv work
- The only thing i've not tried is using windows drivers on the card ... 
don't have windows on the machine.
- I've tried 800x600, 640x480 and some other modes. 

Always the same result.  Bands at the top and bottom of the screen.
There's always also some interlace flicker on the thin lines in any of 
the MythTV UI...

I've got experience with a Tivo (still have it), so I know what is 
possible:  clean, overscanned, flicker-free video!

I want to acheive this goal...  I understand that doing vertical retrace 
sync is not possible during video playback at this time, but 
fortunately, playback of MythTV video does not have tearing when running 
in deinterlace mode, so this is a nonissue for me... The issue is 
getting the right hardware and a really good quality TV-out signal on 
S-Video..

Can anyone suggest ways to eliminate:
    1) underscan bars
    2) flicker
