I have Ati Radeon 9800XT (Club 3D)
First days my tv-out worked 100% no problems at all anywhere. And then one day when i hadn't changed anything i got these sharp lines in my tv-out which blink and its irritating. I dont know what caused it i've tried to change resolutions and checked wires many times.
The amazing thing is that when i watch movies it doesnt add lines or blink it just adds extra gamma/contrast level which i have tried to override with hardware gamma setups but hadnt succeed yet. If i add subtitles to movie they blink (just subtitles blink) and do all the *%$^*%$^*%$^*%$^ but if subtitles are in the avi already theres no blinking just the extra gamma level.
Heres a picture from my desktop u can se the lines, camera hasnt effected on the lines etc...
