I just installed beta2 earlier this week.
My HDHomeRun & MythTV aren't working consistently.
When I get home from work, MythTV backend is down, and Myth has made numerous attempts to record my shows, leaving behind a bunch of small clips of each show that are 35-50 megabytes each. I can watch most of the clips without a problem, but some just give a black screen.
My Core has problems shutting down cleanly. Most of the time I have to press the reset button, because multiple attempts to reboot in multiple ways (over SSH, from the web admin, from the Orbiter) fail. I wonder if this might be causing the problem.
Here is a pastebin of my log from right before my shows should have started recording, at 7pm, up through when I got home & rebooted Myth around 8pm.http://pastebin.com/m6bd226aa
