This reason alone is the primary reason I am test-driving Sage TV right now. The UI is a bit lame, but I understand it's pretty customizable. Once I get it flowing smoothly, then I'll work on customizing the UI. Once that's done, and it gets the WAF seal, then I'll drop money on the HD-PVRs.
While the rumor about the 2nd MC update later this year possibly supporting H.264 is encouraging, I'm not certain I trust or believe it. "By the end of the year" generally turns into late 1st quarter next year, and sometimes becomes "...well, never!" (see Softsled.)

Very happy convert to SageTV! Finally, watching ESPN-HD in real HD on my HTPC without having to deal with the CableCARD fiasco!
