I have the Lite On DH401S Blu Ray Rom with Power DVD Blu Ray Edition. All my Hardware specs are in the reccomended requirements. I have to say I have had mixed results, on my vista 64bit.

Here are the Discs that play

Shakira Oral Fixation Tour
Bridege to Tereabithia
The Brave One

Discs That Don't Play

Dan in Real Life - was able to watch previews than it froze Power DVD
Good Luck Chuck - Got load icon, froze player black screen
Super Bad - same as good luck chuck

If anyone has this model of Bluray player and software I would like to know what kind of results you've had. Hopefully the log file I sent to Cyberlink customer support will give some insight on my situation. But as it stands now I am hesitant to buy anymore Movies.

I don't have a blu ray rom on my pc myself, but have you tried looking for firmware updates, if there are any?

the movies you say that do work. Do you have any problems with them at all? does it slow down or glitch a bit or do they run smoothly and the ones you say don't work just don't?
If this is true then I would suspect your hardware is the problem but if not it seems the ones that are not working are newer movies in that case I would update your firmware on the blu ray device. Sony changed the way Blu Ray plays movies 3 times so there are 3 different versions out there and from what I have looked up on google the one you have has been around for a while and I would suspect you have the older firmware on it.

Hope this helps.

The firmware update for the BluRay drive was one of the first things I did after physically installing it.

I forgot to add the ones that do play do play very smooth around 30-40% cpu usage on my set up.

Download ANYDVD HD 30 day trial. It should help alot. It gets rid of all the BS copy schemes.

Send your detailed configuration so we can have a more accurate assessment of your issue. You need to be more specific why you are not happy.

I play Blue Ray and HD-DVD on my PC. Its a lot better than the stand-alone player in the market. Its my personal DVR and HD-Player. I also have an ATI 650 Tuner to watch HD-TV and regular TV.

I watch all movies in 1080P. I use it as my computer in 1080P. When I'm working using my pc movies is my background.

video Link is DVI to HDMI
Audio Link is optical from PC to my 7.1 Receiver
Display is 70 Inch HDTV//Through HDMI
Optical Drive is LG: Blue-Ray Writer/Read/HD-DVD/DVD-Writer/Read DL
HD Software is Cyberlink 7.3
OS is Vista Ultimate 64

Later on i plan to update the cyberlink software to full version 8.0

See my HW configuration below..

The first real test if your RIG is working is use SPIDERMAN-3. If it plays then in most probablity you can play all Blue Ray movies.

SPIDERMAN-3 is produced by one of the most PARANOID ANTI-PIRACY COMPANY. You need to make sure that your HW are HDCP compliant and your software is updated to recognize your HW. Even if your video card is HDCP compliant but if you have an old software that don't recognize your video card then SPIDERMAN-3 wont play.

Cyberlink comes with Cyberlink Advisor to check the compliance of your HW. The common problem is the Cyberlink software is outdated. The version that i got don't recognize the 8800GT video card on my PC. Get the software updated.

I don't have an issue with my optical drive. My drive is SATA. If there is potential issue with the drive that would be the laser head to read the disc and the interface for high DMA data transfer.

I don't have an issue with Vista-64 with respect to playing Blue-Ray

Cyberlink customer support is nothing different from the complaints that you will read from this forum with respect to other companies.

I have not check my CPU utilitization but i have not encounter any PAUSE or slow down when I'm working and watching movies. My video card 8800GT is fitted with HD hardware accelerator so most of the work is done by the video card not the CPU.

ASUS P5KPL-VM mATX Board
eVGA 8600GT 512MB Card OCD to 675 core and 727 for Ram (Sometimes)

LG DVD lightscribe burner
Lite On DH401S Blu Ray Rom with updated firmware
Cyberlink Power DVD 7.3 BD edition
SPI Sparkle 430 watt PSU

Graphics card is hooked to 32" Seanix LCD through a DVI to HDMI cable
I did contact seanix and they said 32" HDTV us HDCP compliant

Cyberlink HD advisor gave green lights all across the board, I checked this before I bought it.

CPU temps are around 30 idle and 59 when gaming
internal case temp is 25-27
GPU temp 51 idle 59 gaming

Hopefully I didn't leav anything out

I don't have blu-ray yet, but we had problems last year with a Lite On DVD RW that did not want to recognize all the data DVD's kept our anime fansubs on. It also didn't want to recognize a few game DVD's like HOMM 5 and we had to eject and reload a couple of movie DVD's. We ended up replacing it with a Memorex DVD RW and had no problems.

It was a lightscribe too, but I don't know if that had anything to do with it. It was the only optical drive I'd ever gotten from Newegg that disappointed me.

My recommendation is to spend the money on a Sony Blu-ray drive. Until we see more manufacturers, we probably won't see perfect implementation of the standard. I'll let everyone know how I do with a Sony Blu-ray when I get one next fall.

Do you have the latest driver from NVIDIA? Have run NTUNE in your PC?
I did update my BIOS, drive firmware to the latest.

Cyberlink sent me a software patch to enable me to play. Prior to that i get the same issue as you have. Once i got SPIDERMAN3 to play all of my Blue Ray runs normally.

SONY drives are very reliable. This is my 1st time to use LG but so far this drive is doing what it's suppose to do. LG BD/HD drive is common to computer store.

Can you to try to disconnect your standard DVD drive and play a Blue Ray disc on your light on drive?

Here is the weird thing with drivers my card being eVGA, I went to their site and the cyberlink advisor had a red flag on the video card driver. So I went to the nvidia site and got their driver and got green all the way. eVGA's driver number was 169.44 released Mar 6/08 nvidias driver was 169.25 dec 20/07, oddly enough cyberlink advisor likes the driver from nvidia better. By BIOS update do you mean on the video card or the mobo? I do have nTune that is how I overclock my lowly 8600gt by about 25%. So with respect to what leon2006 is saying should I rent spiderman 3 and get cyberlink to send me a patch to fix my bluray woes. I have been getting email support from cyberlink, it sucks that you have to pay to talk to an individual with cyberlink, but I did send them the log file from their advisor program at their request.

Another weird thing is the Superbad movie has 2 discs 1 for movie and 1 for special features. I guess later I found the special features disc plays yet the actual movie won't.

Now this would be my last resort is to do a clean install of Vista, just to get rid of any bad software that might have gotten on my system. I am usually very careful and only install the essentials.

I got the pioneer reader.
No dramas at all.

Rented Planet Earth series and it froze half way thru the 2nd disc, was such a good series i purchased it and its fine, so musta been the disc.

Otherwise BR is aaaallll good

Black screen is what i normally get when i don't get green lights from the cyberlink advisor.

Did you get green light(Cyberlink advisor) for your Blue-ray drive (from light on)? Its hard to assess your drive since mine is LG.

Bios update i mean for the mobo.

I use 169.25 for vista-64 driver from nvidia.

Getting support from Cyberlink is a pain.
