'DVD Play' button problem.

Dudes, just found out a very strange thing. On one of my machines, where the DVD play function didn't work, I have changed in the display-properties, the rate of the Monitor from 85Hz to 60Hz, and suddenly the DVD play works! It looks like, it is only working with 60 Hz. I also tried 75 and 85, but always get this message that the video-stream couldn't be rendered properly. Can please someone of you check this out too, to see if this is the reason. I'm just curious.

i can use the dvd-play button fine. whenever i press it, it says 'no valid dvd files found' (or something like that), but then i hit continue and it plays fine. i run an ATI Radeon 8500 at 1600x1200x32 at 70hz on winxp.

@rect This message apears, when there's no VIDEO_TS.VOB file existing! But since we don't use menu's all the times, this file isn't needed. In that case, just ignore this message.

Plays fine on GeForce 3 at 1024x768 on high color with a 85 refresh rate, after clicking the no disk button. Derrow, if you get a chance would you take a look at this thread. Thanks don

Plays fine on Matrox dual head G450 at any combination of refresh rate and resolution. All works like a charm.

Very interesting. I had the prob with a Matrox Dual Head G550. But also have a G450 on another machine. Will do some more testing :)

i have a problem where the dvd plays but the menu files will not display and all i get is a black screen. i can click around and get it to do things but it is very annoying not to be able to see the menus. im using a radeon 8500 for the record.... anyone else have this problem?
