no audio_ts on dvd why?

[Darklistener]

Hi
I saw some dvds lately which have no audio_ts folder on it.
Someone know why?

AUDIO_TS has to be on a DVD disc to be 100% DVD compliant. Most DVD players play the DVD if that folder isn't on the disk, but there is a possibility that some players wont...

Just a mastering error I guess :D

Hi
I know that all
I got the answer I wanted from D3s7 on irc
it seems that some appz don't make a audio_ts
don't know how the ntsc version of buffy season 2 disc 1 looks like but the pal dvd has no audio_ts
the company who made it have also made some encoding errors

a lot of DVDs here in japan only have the VIDEO_TS folder - i wouldn't worry about it too much. i just add the AUDIO_TS folder when i backup the DVD anyways
