Recompressing from one lossy format to another (the MPEG de/recompression) is going to reduce quality, as are your RGB-YUV color space conversions. You really want to capture to uncompressed YUV, then compress that directly to the final MPEG. I've had good success capturing with the GPL'd VirtualDub for Windows. Ben
