Irritation factor: 10.0 --my experience factor: 1.0, novice, but tech savvy--> I have a Dell XPS 16 laptop running Vista 64-bit, with Cyberlink PowerDVD 22.214.171.12401 [BD Live Version with TrueTheater] I can no longer play Blu-rays on my laptop. I don't own very many, recent issues are rentals - which may be part of the problem? Dell, per usual, is useless. I purposely bought the system I did --with the Blu-ray DVD drive so I could watch any media (incl blu rays) at home and on the road. I first experienced trouble when we bought a flat screen HD tv over the holidays and tried to hook up the laptop with an HDMI cord. Now no blu-rays will play at all (regular dvds work fine) In truth I hadnt been very interested in the Blu-ray part til we got our new TV. I thought prob may be the HDMI cord being connected at first (we watch Netflix- no prob) but disconnected HDMI & recently rented blu-rays are no go. I am really angry at the apparent obsolescence built-in to this item I paid a pretty penny to add on to my laptop at purchase. In my on-line research I came across a comment regarding "updating your video hardware drivers" but this follows comments that updates of PowerDVD can cause this! (and I just updated!) My laptop does auto updates, but not sure about the DVD/bluray drive. This is my third time sitting down to try & resolve this, and all I seem to find are --"the industry sucks" type commentary--Help!! I need some direction here.
