That solution won't work for those with blu-ray as it breaks blu-ray playpack using modified drivers.

Better solution is to use WHQL signed ATI driver for those with blu-ray such as Studio15 & 17 notebooks like mine!:emotion-5:

Thanks for your comment. I did not know that. My 1537 doesn't have a blue-ray, so it works fine.

Hi,

I want to update the drivers and, after a lot of reading in forums, including this one, I think I have a pretty much good idea on how to proceed... BUT!, being in the cautious side, can anyone publish the steps they have followed to get this done successfully?  I am a happy owner of a DELL Studio XPS 1640 with an ATI Mobility Radeon HD 4670 and willing to be able to play Blue-Ray's.  I am also using Win Vista 64bit and use my laptop for gaming as well.

Many thanks!

I think you should call Dell. Once i experienced such a problem in my desktop pc, it turned out to be a hardware problem. You might need to replace either your graphic card, or the motherboard.

well actually after doing some more reasearch it turns out that windows 7 doesnt like hardware acceleration...so if you turn that of the problems should go away...i have my fingers crossed...
