Hello everyone!
I have a few posts on a few sites about the same problems that others seem to have...not playing, etc.
I found out from Best Buy computer Geeks (who worked on it for me...for a price) that it was a simple video card driver upgrade to windows 7. Now my version 10 Ultra plays blu-ray but has a "skip" every second. This is one that I, nor an in-house technician, has an answer to.
My XPS 1530 is great but forget Dell...their support is non-existent. You can't get anyone that is not from India...not even if you offer to pay for the service.
On two occasions, they told me they need to reinstall the operating system...that is their standard answer. And, they are completely wrong.
In closing, I love the version 10 (once I can get rid of this skip) and I would never buy another Dell's support. I will pay Best Buy to work on it.
Good luck everyone...
