HD) have incorrect recording lengths. A two-hour recording will typically show a total recording time of about one hour and 40 minutes, although the recording is complete with no missing chunks (jumping to the last minute of the movie's OSD length does properly takes me to the last minute of the actual recording). For example, a snippet of _The Paper_ recorded from Showtime HD that, according to my watch, took 30 seconds to play, will according to the OSD have taken about 26 seconds. This issue does *not* occur with recordings from any other source, whether 1080i/720p broadcast-network affiliates (including movies they broadcast in HD), 1080i all-HD channels like HDNet/HDNet movies and Discovery HD, or analog cable channels. Even more peculiarly, this also does not occur with other video on the affected premium-movie channels; for example, with a just-recorded recording of _Robin Hood: Prince of Thieves_ (150-minute recording the OSD says is two hours and 16 minutes long), the commercials for other movies ahead of the movie itself, at the top of the recording, all play with proper elapsed time, but the movie itself plays with the aforementioned slow OSD time. I presume the isue has something to do with the difference between films' 24fps and the NTSC/HD 29.97fps refresh rates, but am puzzled by why this is only an isue with the aforementioned 1080i channels but not the others. I suppose this could be related to #1693 but I have never seen OSD times doubled. This is an issue I've noticed since first setting up my MythTV box six months ago, on 0.18.1, and has continued through 0.19 and 0.19.1 (all through the ATrpms packages). The recordings are, again, complete, and otherwise play fine at the normal speed. They are *not* sped up in any way; I've tried playing the affected recordings at 0.8X time, approximating the 24/29.97 difference, and that's clearly too slow. (If it matters, I use Bob deinterlacing, but I use it everywhere, including the recordings from the sources without this issue.)",defect,closed,minor,unknown,mythtv,0.20,low,duplicate,osd slow incorrect time times duration length recording 1080i cable movies,,0
