I personally use Beyondtv 4 and love it. The selling point, all the way back to v3 was the transcoding. It will automatically convert your raw mpeg2 files into smaller mpeg2, wmv, or divx (avi) files
I leave it doingthis overnight so Everytime I show up all shows except the brand new ones are in divx. It REALLY saves you a LOT on HD space.
MythTV is very nice, but it is more user-friendly to "tinker" - people who have the time to mess around with their PVR. Beyond TV and MS meddia center 2005 "jsut work." don't get me wrong, myth is great and it works fine by default, but you'll get the customization bug and you'll be trapped forever
Unfortuantely I have not kept up with sage TV but I have heard good things recently such as how it now supports transcoding as well.
