[MPlayer-users] Problems with NTSC - summary

[Dominik Szczerba]

  Hi,

Thanks for test results. Yes, now I get also good length when I choose 
24 instead of 30 which is reported by mplayer (which is quite 
confusing...) However, I have still theese (and other mentioned before) 
problems with some particular vobs (of unknown origin), maybe it is just 
them that are broken... well I just have to get the originals somehow 
and check with streamdump.

And still I get some NTSC DVDs play/rip on one dvdrom, but not on 
another one...

But this one is finally fixed! So I dont have to worry about region 
encoding, woaw, this is really great, there are quite some nice 
ntsc-released-only dvds out there!

Thanks to all who helped
DS
