Have a TV tuner and an nforce2 board?

[Cyrus Adkisson <lists@xxxxxxxxxxxxxxxxxx>]

... then I need your help.

I've tried getting closed captions via the program ntsc-cc with many 
different combinations of video cards and nforce2-based motherboards 
using kernels in the 2.6.9 and greater range. I've noticed a pattern 
where recent and moderately-old MSI boards are producing garbled closed 
captioning (see below) when left running for 5-10 minutes. Other brands 
(Shuttle, Aopen, Soltek) don't seem to have any problems. Also, when 
using an MSI board, additional cards (up to /dev/video3) seem to produce 
normal captions while /dev/video0 + /dev/vbi0 produce bad captions.

To run a quick test, open a terminal and record a video with ffmpeg or 
mencoder. (be sure the frame-rate is set to the NTSC standard 29.97 -- 
you can simply add "-r ntsc" to the ffmpeg command line -- or else you 
will ALWAYS get garbled captions. Then, in another terminal, run 
"ntsc-cc -cp -d /dev/vbi0" or the vbi associated with your card to get 
captions output. Let it run for 10 minutes or so. If you start to notice 
dropped letters... like the decoder is only picking up half of the 
letters it should, you're getting garbled captions. Please post your 
results to this thread. Please note the brand and model of motherboard, 
brand and model of video capture device and kernel version.

Thanks for your help.
