This should hopefully be a quick and easy to answer question. Is it possible to have a blu-ray disc drive for a PC that wasn't designed to read dual layer blu-ray discs?

Basically I've just tried PLAYING a film on my PC but the disc couldn't be read. I tried the film on the TV's blu-ray player and it worked fine. I tried another blu-ray film (on the PC) and it played fine. The only difference between the two discs is the size (the one that worked was 20 odd Gb and the one that wouldn't work was 40 odd Gb).

Btw Disk Management shows the the size and that the disc is healthy, whilst the disc properties shows 0/0 BYTES free but at least recognises the disc type. (Idk you tell me???)Okay never mind. I hadn't bothered to take the disc out all day and whilst installing 'Mail' from Windows live, not doing or even LOOKING at anything else, the disc loaded and my movie software booted up... Random.

Why can't I have normal computer problems like normal people?Just as you stated days ago...all you have to do is post here...and things fix themselves... And now it's not working again... And just to be confusing it worked after a restart yesterday.New thought! Do retail blu-ray FILMS come in different formats like the re-writable blank discs do i.e negative or positive?

[Note: Firmware update/re-install did not help.]

No that's only DVD's sorry my mistake, I've been misreading things again...

Oh yeah, I forgot to mention. It works with some dual layer blu-rays.Writing it off as a poor quality blu-ray drive. Well, it was only a cheap one. Still, would have expected it to work FULLY and properly.
