11304	Judder and incorrect playback timer when FPS changes	Brian <knappster_1@…>	Jim Stichnoth	"I recently added an HDHomerun Prime and found that when I watch some content on cable channels in HD, I get judder and the recording lengths are incorrect (until the recording completes at which point it seems to self-correct).  It seems to happen on 1080i recordings when the FPS changes (show is 24 fps, some commercials are 30 fps).  To fix the judder, I have to exit the recording and start playing from the bookmark again.  It seems to play smoothly until the next commercial.  It also happens on live TV.

Example:[[BR]]
(1) 8:00 pm - Burn Notice begins recording on USA HD (1080i 2 hour recording)[[BR]]
(2) 9:00 pm - I begin watching from the beginning of the recording.  Total length of recording reports approx. 50 minutes (should be 60 mins)[[BR]]
(3) First commercial break - Skip forward past commercials, now there is judder in playback[[BR]]
(4) Exit to ""Watch Recordings Menu"" - Play from Bookmark[[BR]]
(5) Playback is fine until next commercial break[[BR]]
(6) Repeat steps (4) & (5) with every commercial break until finished watching[[BR]]
(7) When the end of the recording is reached, it is at 1:41 of 2:01.

I then went back to Live TV and watched part of a rebroadcast and turned on the Playback Data on the frontend.  I noticed that when the show was playing the FPS was 24 (jumped around between 23-25).  When the commercials came up, some were the same, others were 29.9 FPS.

FWIW, this seems to be related to an incredibly old ticket #1941, which was closed due to being a duplicate of ticket #799, which seemed slightly different and has since been fixed/closed.

I am using LinHES R7.4 (arch linux, Mythtv 0.25-2).  I would be happy to provide more information if it can help.  I have not seen this issue on the local channels, which I have watched in HD for the last 2 years with the original HDHomerun.  I have only just recently gotten the HDHomerun prime so I don't know if the issue was there with previous versions of myth, too."
