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.",Bug Report - General,closed,minor,0.27,MythTV - Video Playback,0.25.2,medium,Fixed,,,0
