HTPC Will not play ball

[Sparky]

Firstly Merry Christmas,

My new HTPC is having some teething problems
Everything is fine upto the point that i try to play DVD etc [it just hangs] All the software ive tried using gives the same message "Not responding ...."

System is :

CPU Type Intel Pentium 4, 2018 MHz (20 x 101)

Motherboard Name Asus P4S8L (2 PCI, 2 DDR DIMM, Audio, Video, LAN, IEEE-1394)

Video Adapter NVIDIA GeForce 6200 (256 MB)

Thanks to anyone who has time to help and once again Merry Christmas

Will try a new cable but the system also hangs when trying to burn a TS file.Could this be down to the cable too?
