Wouldn't it actually put *more* stress on the system to transcode the output from a > PVR-500 card to MPEG-4 since the system has to decode the MPEG-2 stream in addition to encoding the MPEG-4 stream? > The encode to MPEG-2 happens on the card in real-time with no CPU impact. The encoding from MPEG-2 to MPEG-4 happens non-real-time (like commercial flagging) after the recording so it is CPU intensive, but can be run "nice" so it doesn't impact other processes.
