Can you identify how many pixels width are being captured? I found a similar problem (which I mentioned on this list some while back). I'm using a PAL tv signal, and my bttv card doesn't do scaling properly if the requested width is greater than 768 pixels (which does happen because of the way the driver I'm using---0.7.64, IIRC---works). If you use the XFree v4l module, it restricts the max width to 768 so the problem goes away. I patched the driver to fix this and it's worked fine for me ever since. In testing, I identified that the problem only occurs at certain display heights (e.g. it doesn't occur if you're only showing one field...@288 pixels) Alternatively, it could be that bandwidth thing again :) -- Jonathan Paisley paisleyj@xxxxxxxxxxxxx
