Description (last modified by )
The internal DVD player has a problem when trying to play VOB files that have been ripped from DVDs without a seektable. When attempting to skip forward or backward while playing a ripped VOB file through MythVideo?, the video will freeze and then one will hear strange audio for approximately the length of the skip that was requested (e.g. 5 seconds, 30 seconds, etc). After that, the video and audio start playing normally at the point where the skip was supposed to jump to. The "strange audio" sounds like when one seeks through a track on a CD player.
Skipping forward and backward work correctly when playing the original DVD using the internal player. The problem only manifests itself when trying to play a VOB file that was ripped from a DVD. Also note that the problem did not exist in myth 0.20.2.
I am using MythTV version 0.21-fixes r16838. I have also applied the following changesets from trunk: [16360] and [16836]. (Note that the problem still exists without 16360 and 16836, though; I've applied them for an unrelated problem).

Uploading the requested log.
Note that the video freeze and skipping audio occurs while the log is being filled with the lines that read:
NVP::AddAudioData?():p1: Audio buffer overflow, audio data lost!

I uploaded what I think was the requested log data about three weeks ago. The ticket still says "infoneeded," though. Is there some other data that is needed that I did not upload?

as stuart morgan mentioned in an earlier response to this ticket, individual vobs require a seektable. this is not a full iso. run mythcommflag --video on the vob to generate a seektable.

There is nothing in the ticket view that I have access to that says anything about running mythcommflag. :-( How do I see the full ticket log?
Regardless, I am reopening the ticket, because running mythcommflag does not fix the issue. The same problem exists even after running mythcommflag --video on the vob file.

I recant my last update to the ticket. I re-ran mythcommflag and it does fix the issue. Apparently, you must give it the full path to the vob file or it silently does nothing. Maybe that was in the ticket entry about mythcommflag that I cannot see. This ticket can be closed.
However... Did 0.20 not use seektables? If it did, then why are they not valid when upgrading to 0.21? If it didn't then maybe there should be some documentation somewhere that instructions people that they need to build seek tables for any vob files they had previously ripped in.
Thank you.

Can you try this again with Current trunk? I've just tried it on a few vobs and don't see this behaviour.
If you still see it can you supply a 10-20 meg clip(post a url to the ticket?) ?
Thanks

Closing ticket as requested information has not been provided. Please re-open if this continues to be an issue with trunk.
please attach the "mythfrontend -v playback" from the start of the playback to the time you encountered the problem.
