Vob & Mpg not playing on ext. desktop

[KenKelley]

I should have put a little more info here. Also, I have turned in a ticket and MTU is thinking Bug because of my situation (not many folks use .vob video files) but after seeing this post, maybe you all have come up with a work around or remedy MTU isn't aware of.

1st Computer: Dell XPS 1701
OS: Windows 7 Professional
Memory: 8gig
Video: Nvidia (3gig memory)
Hoster: 4.32.12 (with all required Windows settings)

2nd Computer: Dell Inspiron 17R
OS: Windows 7 Home Premium
Memory: 6gig
Video: Radieon (1gig memory)
Hoster: 4.32.12 (with all required Windows settings)

VOB files are copied to my hard drive from "Pioneer Karaoke PDL Series" DVDs (about 650 and I have another 100 files copied from Ubest DVDs). These files worked flawlessly when I was running an HP with 2gig ram, shared video memory, Windows XP Home (Media Edition). I had tried the K-lite codecs on that laptop but discovered ffdshow worked better (it allowed for the mux button to operate for these particular files, K-lite would not).

I have installed Windows 7 Codec Pack from a site that Microsoft recommends for codec updates and now the Mux button works properly on the 2 new computers. The video however will only play in the singers display when it is on the laptop screen.....

I have updated both computers with all the software, driver, and bios updates from dell as well as all Windows 7 updates.

I have to say, the computers are great, Hoster 4.32.12 is even better than ever when any other file is played through it; CD+G, MP3+G, .DAT, wmv, etc with all other video file types being played showing up on the singers display and the mux button working properly weather or not I have a codec pack installed.

When I utilize an Insta Button to play a .vob file, the video not only shows on the singers display on the extended monitor but also on the preview display on the Hoster console! (Not in sync however) Never saw that before.

Just cannot quite figure out why the video from a .vob file disapears from the singers display when the display is moved to the extended screen.

One other thing, I have attempted to run non-karaoke .vob files as I would a karaoke .vob with the same results.

Thanks in advance for any assistance you might be able to render!
