Hey every one,

I have two hard disk istalled on my computer I can Play This Ifo file
on one of them with media player classic But when I made a copy of the folder
Video_TS to the other hard drive and played it with media classic
I got the message "Incompatible disk and decoder regions" shortly the same file can play on one hard disk but can't play
in the other hard disk I don't Know the type of disk one
but the 2nd which does'nt work is Western Digital

 

Are you running Vista and is it an external hard drive.

 

First thank you,
You are right I'm running Vista Home Premium
and the 2nd Hard Disk connected to USB

 

I don't have Vista, but there are a posts regarding this on Afterdawn
Reference is usually to "UAC" (sorry, I don't know how to turn it on or off)
