You said this (and I believed it :-) so I tried it. I got a really ugly green image with lots of pretty purple dots (it reminded me of my college days). Does it work for you? vic-2.8 wants to use YUV_PACKED mode. It looks like there is dma-program support for this in the current driver but no pixfmt, so "oformat_meteor_to_bt()" failes w/-1 (I verified this - it happens in my driver). There's also a comment in the code to the effect that pixel formats for YUV_422 and YUV_PACKED are missing... I'm not sure how to fix this but I'll look into it. any insights? I added entries to the mapping tables to get the right dma program to be built (that was easy), but still produced a nice green image (only 1/2 of an image, oddly) with purple highlights. ps: thanks for the tip on the S3 card & xfree86 - I'm going to get xfree86a and try the new "anti snow" fix
