Yeah, but I'm pretty sure the PVR-500 outputs MPEG-2, not MPEG-4, so
this kind of defeats the purpose of owning the PVR-500 (assuming he
purchased it with the MPEG-2 output in mind). 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?
Of course the CPU and the harddisk will get more busy, but the CPU will only work on the transcoding when it has nothing else to do.
I record in MPEG2 (PVR-250) at 4.5 Mbit/s and transcode almost everything (except what I want in DVD-format) automatic to MPEG4 at 1.4 Mbit/s. So my recordings are initially at 2 GByte/hour, but after a while they are at
0.63 GByte/hour.
I have a 1.6 GHz AMD processor and it does the work very nice. It can transcode almost as fast as record, so a couple hours after a movie has been recorded, it is already transcoded.
