It isn't the playback that consumes the CPU it is recording analog to disk. It has to encode it to MPEG2 before it sticks it on the disk. It takes at about a 1GHZ machine to encode a single TV stream to MPEG in real-time. To do more than one turner, more GHZ . That is why a premium is paid for cards that have hardware encoders on them. Digital TV is a different story. It is broadcast in a MPEG2 transport stream that can be saved directly to disk. No encoding to worry about. _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
