Great patch Shane,

I'm have applied 2335_fix_2.diff and dtv_ResetForNewFile.diff to
revision 14496 on both my server (backend+frontend) and living room frontend

Generally I have had no problems with livetv or recording playback. Show
transitions work fine with no hangups.

But one time (yet) I noticed a problem in livetv. On the living room
frontend I had paused the livetv, while I attended some other business,
and during the pause, there was a show transition on the backend.
When I got back, I could not resume the livetv. It was sort of "stuck"
on looping over a couple of frames. I could jump forward to the next
show, and playback resumed (allthough it got stuck some time later).
Unfortunately I have no logs of this event.

This was with my IVTV card PVR500, not a DTV card.

I agree. I've been using it now for a couple of weeks as well and not
a single problem!

Re: Ticket #2335: LiveTV hangs when a recording is finished and a new on starts (no channel change) [In reply to]

I have tested the latest patch on this ticket, and the lockups have returned. The logic that determines whether it is streamed or not appears to be incorrect. By changing line 749 if (ringBuffer->isDVD() || (ringBuffer->LiveMode() && recordingHasPositionMap)) to if (ringBuffer->isDVD() || ringBuffer->LiveMode() || recordingHasPositionMap) fixes this. Apparently, recordingHasPositionMap is not getting set correctly.
