Lite-On's External Blu-Ray

I’ve got a Lite-On DX-4O1S External Blu-Ray Drive for my Acer Aspire 5720 Laptop. I checked online for specs on the Acer with regards to HDCP capability and it seemed fine. I even tested it out by downloading legal x264 and H.264 (Aren’t these the compression codecs for Blu-Ray?) enabled video clips and they played smoothly on the 5720. My problem is when i played a Blu-Ray Disc on the External, everything else worked fine (the trailers, the making of the movie, the extra features) except the main movie itself. The main movie fell under a severe lag with both audio and video stuttering. Is this an issue with the drive, the disc or my system?

:confused::confused::confused:

What are the specs on your computer? Blu-ray if encoded as vc-1 will bring a older machine to it’s knees. I have a dual core intel processor running at 1.7 Ghz which has no trouble playing mpeg2 Blu-ray titles but when it comes to the titles encoded in vc-1 it can’t handle them. Everything is slow and the audio looses sync.

Specs:

Intel GMA: X3100
Windows Vista Home Premium
DVI-D Port (HDCP support)
CrystalBrite TFT LCD with 1280×800 resolution and 8ms response time

Dont know if you need more specs but it’s what i could gather off the top of my head…

The funny thing is there’s a variation to the same model (exact same specs as mine) with an optional HD DVD drive…

And how would I know if the blu-ray disc is vc-1 encoded? Thanks for replying!

Oh I should add…Intel Core 2 Duo

Core 2 Duo, but which one?

C2Ds have a wide range of speed…

Oh sorry…

Microsoft® DirectX® 9.0 and 10.0 support

Actually, I just contacted Lite-On…and they say that it could be a problem with the software I’m using to view BD movies…Cyberlink’s PowerDVD 7.3 BD Edition.

The tech guy mentioned updating my security codes on the player which would possibly solve the problem

You and I are in the same boat. Note the system requirements listed by the Power DVD people…

Doesn’t Blu-Ray automatically allow for 720p playability? I read that in several articles…so my resolution of 1280 X 960 should be able to playback a BD…and yea i meet the other requirements…including Intel on Vista…anyway thanks for the reply…and the stats! Much appreciated…I’ll let you know if the update patch worked

By the way, I just checked a few things over the weekend. I rented I Am Legend on Blu-Ray which is a VC-1 encoded disc and it played quite fine with very minor jerks in video here and there but played well overall. I’m assuming that my system can handle VC-1 now as i’ve tested it out.

I also tested Stargate (MPEG-2) and it played smoothly.

I guess this kinda puts me in a better position hehe. Thanks for the help and info though, Smabbage!

I appreciate it!
