bluray on PC 4 days of work, no results

[10bob]

Hi!,
New to this forum and probably my last resort.
After some thought the idea came to me to extend my home cinema system with a pc that could do all sorts of beautiful multimedia stuff.
View movies, pics and listen to music which were all stored on my pc.
This is the setup;

Mainboard Gigabyte GA-MA74GM-S2H
Processor AMD X3 8450 AM2+ 2100
Memory 4GB Kingston
HDD WD 10EAS (1TB)
Graphics NVIDIA 9400GT (512MB) HDCP ok
Powersupply Zalman 500W
Media lab IR control
As an afterthought I added a Plextor px-b300sa.


Putting it together was easy enough and sure the whole thing was up and running in a jiff.
With XP sp3 as the OS because I still had a license lying around.
I bought a blu-ray (Firefly ) disc to do the blu-ray testing part.
The pc was setup with a 19” LCD monitor with the idea that once all worked to satisfaction it would be hooked up on my Samsung 46 “ LCD TV via a DVI to HDMI cable

Plextor supplied Windvd 8 as the player for Blu-ray material.
It crashed as soon as it sniffed at the disc. Does play avi’s and dvd’s but that’s about all.
Tried powerdvd 8 ultra, it accessed the disc but stopped by itself.
VLC player was no alternative either. (But plays mkv files in 1080p, astounding.)
I found that XP couldn’t access the disc either so after some googling found out it needed UDF 2.5 support and tried everything again, no result. (But XP could now access and read the disc.)
Took the whole thing to another PC that had Vista Ultimate SP1 on it and repeated the whole story, still nothing.
Both the advisor from windvd and powerdvd found only the CPU in wanting but do not believe this as the second system has a Core2 3Ghz CPU implemented.
Did not install any other codecs that where not supplied by the players.
Reading in forums, the few that have built their own system, many seem to suffer from the same problem with different brands of drives.

Presently I’m at the end of my wits and although I’m not a complete idiot working with pc’s do not know what to do next.
Do any of you have solution or a pointer to this problem?
