Description

I've noticed that on a frequent basis, I'm not longer able to utilize time stretch on several of my recordings. It appears to be on HD recordings, as I haven't seen the issue appear with SD recordings. I've attached a log with mythfrontend -v playback.

I played the file back twice. The first time, when I enabled timestretch, it froze for about 3 seconds then played maybe 2FPS after that. I then exited and replayed the same recording, enabled timestretch, and video froze until I exited again.

When increasing timestretch above 1.0, the picture will freeze but the sound will continue to play. You can hear the speed of the sound increase, so time stretch is working there. To fix the issue, I have to exit the recording and watch it at 1.0. Many of my other recordings act fine with timestretch (HD and SD) and timestretch has worked great in the past on this hardware in previous versions. However, this appears to happen very frequently now.
