Video Files with the Following Configuration

[pcgumshoe]

I'm having trouble playing .vob files that were ripped from DVDs in Hoster, could it be that the Graphics card isn't fast enough?

The Configuration of the system is as follows:

Windows 7 64bit
K-Lite Codec 64 Bit Pack
Pentium Dual Core E5400 2.7GHz
2 Gig of Ram
ATI HD 4800 Graphics Card

I can load the file and play it in hoster if the display windows is on the desktop but not on the secondary display which is TV, I just get a black screen and the audio.

Any help or confirmation that the graphics card won't work would be appreciated.
