Well the cmyth pvr on FireTV worked out of the box for me since at least 13.0rc1 (on libstagefright). Playing 1080i Fios TV, no dropped frames or de-interlacing problems (don't really know how to look for that), actually no discernable visual differences between FireTV and my core-i7 desktop or xeon server. Or maybe it's just all the channels I watched are all super-low bitrate.

I'm on Comcast and using HD Homerun Prime with MythTV backend. My highest datarate stream is probably ESPN, coming in at around 15Mbps. Jerky playback is especially evident on this channel due to the presence of the scrolling ticker at the bottom. The lack of de-interlacing shows up as subtle horizontal lines.

You can view the video bitrate by plugging in a keyboard and typing 'o'. This will also show you any dropped or skipped frames as well as the buffering status. In my case, the drop number continually ramps up on high bitrate MPEG2 videos. I see the CPU usage on CPU0, CPU1, CPU2 vary between 50%-75%. Strangely, it seems to stay high even when paused.

Does my CPU usage seem normal to someone who has AFTV working with MPEG2? Maybe I got a bad device or some other setting/program is consuming my CPU.

I'm also on Comcast and using HD Homerun Prime. I am using XMBC RC1 connected by ethernet. I have both HW accelerations checked. I am running it two ways on my FTV. First way is with Windows 7 NextPvr (NPVR) backend and second method is direct from DLNA using the Prime. NPVR picture on FTV is fine but frequent channel changing seems to cause XBMC to close. NPVR when I scroll to record locks up the FTV and I must hardware restart it.

I found a XBMC RaspberryPi wiki on how to set HD Homerun Prime up without a backend using DLNA. Problem with DLNA is that it stops and breaks up occasionally. Most of the time the picture is fine.

I debated about using WMC backend. WMC is on the same W7 machine as my NPVR backend. The W7 with WMC and NPVR is connected to an first generation Sony 40" Google TV and I have key mapped the Google TV remote to work with the PrimeTime Google Guide and WMC, and do not want to break that with the WMC XBMC backend.

Any suggestions on making NPVR work better, or fixing the pause and pixelation using DLNA. I will have to try the 'o' with my Logitech K700 keyboard to see what is going on with CPU's and buffering.
