    Remote Frontend Fails to Play anything After last apt-get update (1-7-2013)

    Hello Everyone,

    I just moved back to Mythtv after purchasing an HDHomeRun this past fall. Been enjoying mythbuntu so far despite a few glitches (laggy program guide, death of internet streaming plugin, my failed attempts to auto-transcode and export recordings for copying to a tablet, etc). That's probably for another post and I fully expect a few people to smack me upside the head and point out that there are already 50 posts on said topics. Anyhow, on to my real issue!

    I have 2 computers with mythbuntu 12.04 on them: a retired desktop running the master backend/frontend in the office, and an ex-mac mini running frontend only in the living room. So far everything's worked.

    I've added mythtv-updates to my package update list (via that menu option in the system center), which seems to be an issue because I'm guessing it's grabbing nightly mythtv updates. Normally this doesn't pose a problem, but from time to time it's broken itself, requiring me to reboot/wait for another build. Guessing this was my first mistake, eh?

    Anyhow, on to the story: I updated both systems the morning of 1/7/2013 and cycled both. Now when I go to watch either Live TV or any of my recorded programs on the front end, it freezes for 30 seconds, then displays "Please Wait..."....then hangs there in perpetuity. Occasionally Live TV will show the program guide, then a 1/10 second of audio, then freeze.

    What's odd is, the backend/frontend combo system works fine. It records fine and I can watch both live TV and recordings on it without issue.

    I also tried accessing the backend via XBMC's new frontend plugin from my laptop and it looked to be the same issue - the video froze, showed 1/2 a second...waited 30 seconds, showed another .5 second. Always buffering, buffering...

    I've tried cycling all systems involved multiple times with no luck. Is there anything I'm missing?

    From the backend:

    I'm getting a similar error in my log -- but not sure if it's my frontend failing or just the commercial flagging process job.

    This is driving my crazy -- after an overnight of recording, I find a number of crashes on my mythbox, or if I'm watching a show and commflagging is processing, my system "sometimes" jumps to a high load (e.g., load=11).

    Here is a snippet from my mythcommflag LOG

    Re: Remote Frontend Fails to Play anything After last apt-get update (1-7-2013)

    Quick update - I found out this was due to a kernel bug introduced with newer mythbuntu kernels vs my r8168 onboard ethernet (Asus P5B mobo). For some reason it'll vomit under heavy network loads unless you grab the r8168 drivers and build it as a module. Not sure why, but building the module fixed everything.
