OK, I got my pvrxxx problems fixed (I apparantly had my ffmpeg line wrong). I'm having trouble getting a decent recording though. The uncompressed stream is too large for comfort. I've tried: $ cat /dev/cxm0 | ffmpeg -i - -vcodec $v -acoded $a -f $f out.mpeg $ ffmpeg -i /dev/cxm0 -vcodec $v -acoded $a -f $f out.mpeg for various values of $a/$v/$f. So far I can can get mpeg2video/mp2/mpeg, wmv1/wmav1/avi, and wmv2/wmav2/avi to work. However, this formats end up being really pixelated. libtheora/vorbis/ogg wouldn't play in anything (I know ffplay wouldn't get it) I think I got one of the mpeg4 options working, but likewise, it looked like blocky crap whenever there was any motion. Any suggestions? If the video format is fairly low loss, I think I'd be fine using 360x240 (1/2x1/2 max), otherwise, I'd like to use something closer to full resolution. Note: 'cat /dev/cxm0 > out.mpeg' works fine, and looks great - it's just huge (3-4GB/hr). Does anyone know of a format that should work well? The computer is a Optron 185 (dual core, 2.4Ghz), with 3GB memory, and a 7200RPM hard drive. At the end, I have the formats that my install of FFMPEG recognizes with both encode/decode.
