You can use DVTools to create ReplayTV "compliant" video which you can then stream from PC to ReplayTV. I find that using a delay of 0 with DVarchive and a 5040 with a 200GB HDD, I get an average dl speed of 1.45MB/sec, around 25 mins to dl an hour of high quality. At one stage it was running at closer to 1.8MB/sec, can't replicate it. Of course this is with the RTV off and not recording. And I find PowerDVD and WMP both playback ReplayTV high quality with no problems. Using the MPEG2s in an editing program is another matter, all the ones I have puke on it.
