10244	LiveTV: Video frame buffering failed too many times.	ignissport@…		"Since a recent upgrade from 0.24-fixes to 0.25-pre, I've have been frequently getting the error ""Video frame buffering failed too many times."" (usually after a few minutes of playback). This occurs after a frontend hang of about 30 seconds, and dumps me back at the main menu.

== Observations: ==
* I have two frontends. One is running an Intel IGP on IPv4. The other is running VDPAU on IPv6. Both frontends have this issue.
* If I watch the same channel on both machines at the same time, one frontend can fail independently of the other (however, the backend reports using two different TV tuners recording the same channel)
* This has also happened when watching a DVD ISO from MythVideo. NB: I'm watching Australian DVB-T, the transmission codec and resolution is identical to a DVD. The only difference is that one is MPEG-PS and the other is MPEG-TS.
* When I display the stream information OSD, it shows the buffers running at 0% when it fails.
* I get a lot of warnings about writes taking a while to complete. I'm running btrfs raid-0 on my backend (a pair of 1TB caviar greens). It had some crazy IO utilization issues when recording TV in 0.24, but that appears to have been fixed. The IO is not high when this problem occurs.
* I'm running NFS between them, but I have set 'settings.AlwaysStreamFiles=1' on my VDPAU frontend and it's set to '0' on my other frontend and also on the backend. (i.e. it happens regardless of what this is set to)."	Bug Report - Hang/Deadlock	closed	minor	0.27.1	MythTV - Video Playback	Master Head	medium	Fixed			0
