I'm a big fan of watching DVD movie on my computer, even though I've been recommended not to. However, there are a few DVDs that have sound that just wont play. The sound play on the opening splash screens (universal, etc).. but the sound in the actual DVD doesn't go at all, it's just silent.


And no, they're not silent movies.

I use InterActual Player for playing the DVDs. I'm not sure if the DVD zone makes any difference... I've had this problem with 0 and 4 (the only zones I use) but some other DVDs of the same zone don't have this problem.
It might be the newer DVDs having this problem, I'm not sure.

All my DVDs are also PAL. I checked.
