I have a bunch of movies on an external hard drive and when i open them to play on my computer they make a screeching noise and the movie will just show images or will go out to a grey screen theen goes back to pictures of the movie it does not skip ahead. and there is no sound expct for a screaching noise, im sory its hard to describe it HOWEVER when i change my media program and open it with a diffrent program like vcl or quciktime or whatever it works perfectly. When i try to burn these movie that work fine with other programs, it must open with the program becuase when my dvd is done all it is is that grey skipping picture screaching thing. SO MY QUESTIONS is whats the deal with that. why does it work on some programs but not one, and why wont it work with my convert x pprogram how do i make it so it works because i know it works, just not one in program. SORRRY very confusing probably. its very hard question to ask/ describe.
