Hi, the video images I get from a TV card have some kind of very subtle jitter at some resolutions that causes quite a bit of eye-strain (and headaches). The same card on Windows 2000 has the display rock solid. I have a Pinnacle PCTV Studio Rave (bt848) running fine with a Linux 2.2.16 kernel (SuSE 7.0) with bttv 0.7.35. xawtv 3.27 displays the tv images cleanly without artefacts, no snow etc. It uses the XFree 4.02 v4l extensions (with great success). The problem I have is some jitter in the image itself at image sizes smaller than 300 pixels vertically; at 160x120, 192x144, 320x200, 384x280 I get the jitter; at 400x300, 640x480, 768x576. Comparing this to the card's performance on Windows 2000 SP1 (with the "native" Pinnacle drivers), the results I get on Linux are clearly inferior simply because I can't stand watching TV picture there (perhaps a good thing? :->). Where could I start tweaking?
