My HTPC has been running for about a month now and working great. I've watched about 10-12 blu-rays up to this point, but I just got one from Netflix (The Last Emperor) that my computer won't recognize. I put it in the drive and not only will it not play, but when I open "Computer" (I'm using Windows 7 RC) it says there's no disc in the drive. I've tried disabling AnyDVD and re-booting, cleaning the disc, etc. The disc doesn't look damaged, but sometimes you can't tell from looking. I haven't had this problem with any other blu-ray. I tried another disc and it worked fine. So is this just something with this particular title that I can't do anything about? This movie happens to be very long (almost 4 hours) in case that might be an issue. Even if there's not fix for this, I'd appreciate any clarification on what the cause might be.

I have had this happen when the disk has new protection. Have you tried installing the latest version of AnyDVD? The disc could have been damaged as well.

Wouldn't that only be an issue if I was trying to rip the disc to an .iso? I'm just trying to play it, it should be able to play with AnyDVD disabled, no?

That would assume that your new HTPC player software can decode the new protection. Most people I would say use AnyDVD HD just to get reliable playback directly from a disc.

Does your BD ROM drive have the latest firmware applied? What model do you have?

Most likely a damaged disc. Happens occasionally with Netflix.

If a Netflix disc fails in my HTPC, then I try playing in my PS3. Never has the PS3 been able to play a disc that failed in my HTPC.

Mark it as unplayable in your Nextflix account and have them send a new disc.

I have the LG black blu-ray drive. Haven't tried updating the firmware, guess I'll try that. I've gotten plenty of damaged discs from Netflix (an incredible number in fact, I'd say about 1 in 4 for blu-rays), but they've at least shown up in the drive in the past, only when I try to play them they'll skip or not play at all. Plus there have always been visible scratches, whereas this disc looks clean. I've never had this situation where the computer doesn't even see a disc in the drive, so that it's not even possible to try playing it. I guess the thing to do now is to try updating my AnyDVD HD. Thanks for all the tips!

Blu-Ray discs are far more susceptible to damage than standard DVDs. The amount of data that's stored on the surface is packed more tightly so any surface defects will affect far more data bits than the same affected area on a DVD or CD. Unfortunately, some people just don't care and treat rental discs like crap so their life expectancy tends to be much shorter than if you had purchased the disc yourself. I'm amazed at the condition of some discs I've received and I'm even more amazed that some of them play at all.

I've had quite a few BD discs from Netflix that failed to read properly on my BD drive. Netflix has always been prompt in replacing any bad discs as soon as I report them. Every replacement disc I've received to date has worked flawlessly.

Yeah, I always report bad discs to Netflix. If more people did they wouldn't stay in circulation as long as they evidently do. I guess a lot of people worry about getting into trouble if they report too many problems, but if Netflix did that it would have happened to me a long time ago. I've plobably reported 15 damaged discs over the last year, as well as two that never showed up and 1 or two that never got to Netflix after I mailed them. Some people are definitely inconsiderate slobs, they must just toss the discs on the floor as soon they finish watching them. As for discs going missing, it must be unscrupulous Netflix employees. They see a movie they like, pocket it and say it got shipped. Just a couple weeks ago I had two blu-rays that were reported shipped on the same day not show up! They were Casino and 28 Days Later. I guess someone who likes violent movies saw a chance to make a big score!

Also may be your video drivers, I have read that out of date drivers give PowerDVD issues.

I'm using TMT 3. However, I haven't yet updated my Catalyst driver from 9.5 to the new 9.6, just because everything was working and I didn't want to mess with it. Maybe I should try that. I ordered a replacement disc, so if that doesn't play I'll update the video driver.

Personally, I think upgrading video drivers every time a new one gets released is overrated. I've rarely, if ever, had any issues with a particular driver version for any video card I've ever owned. If it works then I see absolutely no need to upgrade it (i.e., if it ain't broke, don't fix it). The only software I've ever needed to upgrade due to new BD discs being released is AnyDVD HD. If you've got to upgrade your video drivers because of PowerDVD then the best recourse may be simply to stop upgrading PowerDVD. That's one app that seems to get worse with every "improvement".

Have you gone on the SlySoft forum and sent them a log file yet? They have a pretty good diagnosis sticky for problem disc's. I really don't think it is a video driver problem, it could be more of a BD+ problem possibly.

I only suggested that because I had some issues with powerDVD and a google result had that as one option. Personally I don't screw with drivers/BIOs/software upgrades unless I absolutely have to, just kind of throwing it out there. Updgrading the drivers did (supposedly) add sound to HDMI/DVI which I dont use because I use it on a projector so I had to turn that off.

So far I havent found a BD that AnyDVDHD (+DaemonTools +PowerDVD) doesnt work with. The only reason I was even looking is that I didnt realize that PowerDVD doesnt deal with mouse clicks on BD... at least the version I have... Once I get another remote for upstairs it wont matter to me.
