20 % CPU and 50 $ RAM ??? That is quite a lot for streaming from a PVR
encoder card.  Could you send the log from vls to this list, maybe it
might tell us more what is going on. It looks like vls is
transcoding/encoding the video instead of your PVR card. AFAIK the
PVR350 encodes the stream itself into MPEG2-PS.
