Sony Vaio Blu-ray problems

[jlee562]

Ok, I'm having BD problems on my VAIO as well...

I've got the VGC-RC310, which has dual core Pentium D 3.20 ghz processorsm 2gb RAM, GeForce 7600 GT, and the Matshita BD-MLT SW-5582. The program is WinDVD BD which came bundled with the computer. Everything is updated with drivers and what not. Hooked up via DVI to a Viewsonic VX225wmb 720P monitor. XP MCE.

House of Flying Daggers, Jay and Silent Bob Strike Back, and Black Hawk Down all play fine.

The Simpsons Movie, Live In Dublin: Bruce Springsteen With The Sessions Band both skip and thus get out of sync with the audio. These discs also don't show up in "my computer" and the BD Drive reads as a "CD-ROM" drive when they are.

I've no clue what's going on, and as it is, I'm already somewhat clueless about the whole HD thing. I've downloaded the pertinent updates from Sony, but these movies still skip.

Consequently, when Win DVD BD is running, it takes up 100% of my CPU load, it does this for the movies that play fine as well as those that don't.

Anybody? Thanks in advance.
