A weird one (DVD video disks not read)

Ok, yesterday got myself a good set of Philips SBC HD1500 wireless digital headphones (Dolby Headphone supporting ones), so needed to check surround sound in action, pulled bestest sounding disks off the shelves. That would be Matrix, Star Wars Ep3, LotR:Ext-Ed and some other disks.

So, i stick in Star wars - drive does “cant read” routine by moving head up and down the track… Drive just wouldnt stop and shut up… Same goes for Atlantis (2 disk) edition (movie disk), so does for Final Fantasy Advent children (both disks). Some other disks refused to be read.

So i stick them into my standalone Philips DVP-5980 and voila, they all work without a hitch…

Mind you, disks are all legit factory printed region 2 material. Drive is regionfree (Liteon 20a1p or some such).

Now, it would be problem solved if drive wouldnt read anything else (throw it away), but it does, DVD data (-+R, RW), DVD video (LotR, Matrix), CD’s. So, it is not that drive cant read…

I’m confused…

Oh, btw, “not reading” problem persists when physically disconnected from IDE channel… Some disks just get read and stop the drive, others keep on spinnind and moving head…

Weird…

I have tried all the usual bits of troubleshooting. Viruses, trojans, spyware absent. Hardware has newest drivers availiable.
Can someone explain all this to me ?

P.S. Not all DVD video disks are being “not read”. I havent tested great number, but so far all this is making me a liiiitle bit concerned. So far its 50/50 ratio of read/unreadable…

P.S.S. And Philips SBC HD 1500u’s are a great fun to listen to Very Happy Expensive, but worth every penny i paid for them…
