This is awesome! I simply downloaded the tar file and placed it in the Update folder, rebooted, got a little scared when it just hung at the splash screen for a while. Then it rebooted itself again and viola, it was running. The PVR client for MythTV seems to work fine, video playback looks good, sound is there, but I only have stereo speakers right now. I'll hook it to my AVR later and see if I can DD5.1 at least from broadcast TV.
I built from the github sources last week and then got sidetracked on local election stuff. It was stable for an entire week just sitting over there. I'm really impressed with how quickly and smoothly this going. I've been using an RPi2 for quite some time, but am looking forward to upgrading to this C2. It's way faster at bringing up the Program Guide from the MythTV client, even the Pi2 took too long to load the 100+ channels of info.
I noticed that we don't seem to have control over deinterlacing methods. Is that right? I can't find any options via the OSD during playback. I'm okay with the way it looks now, I just was wondering about it. I did notice some color banding on a TV channel. Just sayin', not complaining. Again, this is awesome. I'm already anxious to change out my Pi2 for the C2. I have do some more testing though. I haven't tried the Ortek WMC remote control yet.
I was worried about MPEG-2 decoding since one has to purchase a license for the RPi to get it, and I need it. It seems to be doing a great job. I did notice that when I bring up the statistical OSD (O key), it gets a little jerky and buffers during LiveTV playback. I don't know if that's an overlay issue or what, but I really don't care at this point. I'm thrilled! The "O" key shows a playback rate of 25FPS, but I live in 60Hz land. I was expecting 30FPS on the display, but I've seen this before on the RPi2. It may not be important at all.
You guys are great, thanks for everything.
