LG GGW-H20L won't read,play or write blu-ray


I have been trying to get my new LG GGW-H20L burner to work for days but i am running out of ideas.It will perform all functions properly with regular dvd’s but with blu-ray it won’t.
When i try to play a blu-ray it doesn’t even recognize most and when it does play one then it is jittery and the sound is skipping.It will not read or write also to blu-ray.I can play download blu-ray on my harddrive without problems.
I thought maybe i needed to update my video card so i did but that didn’t help.This is a newer system,
Intel dual core E7400 @ 2.8 Ghz,3.5 GB ram,motherboard is [COLOR=black]ASUS P5KPL-CM and i just added this video card [/COLOR]ASUS Radeon HD 4350.

Any ideas Please :confused:

Have you tried different SATA ports, or changing SATA cables, or check out the BIOS settings especially in Main > IDE Configuration menu?
