You're not the only one. If you look back 1 or 2 weeks you'll notice that another gentleman and I posted with the same problem. I still haven't solved it and I've been just exporting the shows to myth video in the short-term just so I can watch them.
It would be nice it we could find a solution. -Todd -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Jeff Wormsley Sent: Monday, March 07, 2005 7:15 PM To: Discussion about mythtv Subject: [mythtv-users] Playback issue with firewire captured video I have a problem with playing back some captures made via firewire. It doesn't seem to matter if they are SDTV or HDTV sources, as I have had some of each. There are two symptoms, one bad, one worse. Bad: Video doesn't play, after about 5 seconds, control returns to MythTV. Worse: Crash. In both cases, the preview panel shows video in the little window for the show in question. Following is a frontend log of the crash situation. Here's the bits I am most worried about: > 2005-03-07 21:51:08.034 waiting for prebuffer... > 2005-03-07 21:51:08.034 prebuffer wait timed out.. Lots of these. I do get some audio stuttering when playback works. CPU is slightly underpowered, so I expect this until the new CPU gets here. > 2005-03-07 21:51:09.366 Broadcasting free space avail > 2005-03-07 21:51:09.387 Broadcasting free space avail Lots of these as well.
