With the new Roamios out now, I'm thinking about switching back to Tivo. I had one of the original Sony Series 1 boxes with a lifetime subscription. The box is long dead, but I still have the serial number / service number. Could I transfer that to the new Roamio? How much would it cost? Does Tivo Desktop allow you to start watching a show before it completes downloading to the PC? I'd prefer to just be able to stream it instead of downloading, but that would work ok too. Can you play MKV files (like blu-ray rips, etc.) from a remote network share on the Tivo? How about from the Mini? I can do this now on my HTPC, but it would be nice to have one device to do it all.
