It looks like the VCSM commits are responsible.
On the latest build, playback of live interlaced SD mpeg2 content via tvheadend triggers the issue without playback starting. The below relates to progressive H264 playback which works fine until playback is stopped, at which point the same freeze occurs, and the same backtrack is generated. This seems to occur directly in relation to code touched by one of the VCSM commits?
