Does your BD-ROM stutter?

[JediFonger]

watching WatchmenC. at roughly 2hr 59min 28second mark there is a stutter.

if you look under the stream folder, that time stamp is where the file 00522.m2t ENDS and 00523.m2t BEGINS.

i've replicated this issue on:
-2xLG GGC-H20L firmware 1.03
-1xLG GGW-H20L firmware: 1.04

so at first i thought it was just my LG that's fuking up, then i tried it on my:
-1xSony Optiarc Slim laptop reader and same problem.

the only places it works smoothly is my standalone Panasonic BD35K & BD60

do you guys actul BD discs played on HTPC BD-ROMs experience problems like this?

oh and before you start pointing fingers@CPU/GPU/etc. it's not any of those. all those optical drives are installed at radeon 3000 and better w/full UVD or UVD 2 decoding, latest drivers on Vista64 or win7pro64, etc. it works smooth as butter, just not on BD discs...

Hypothesis: That point may be where the layer break is; the laser needs to re-focus in order to continue reading, creating a small interruption.

Could be your standalone uses a large enough read buffer to hide the interruption, while the playback software on your PC does not.

Which media player application(s) did you use?

Mine stutters with WinDVD BD for VAIO, even with latest update from Sony (8.20.89). But I have no problem with PowerDVD 7 build 7.3.5711 (Nov 09 Update).

Only when I flex my muscles.

tor, it's at the END of the movie, and if i play it from hard drive, it still 'stutters' on a variety of combination and platforms of Win7 computers. so it can't be SW/HW. there's somn else going on very strange.

it's when 1file goes to the next.

But it's at only one point during the movie, right? It could still be the layer break - the movie doesn't have to be split 50/50 between the two layers.

This though, appears to refute my hypothesis.

A variety of platforms, OK - but did you try different media players?

I agree, very strange indeed...

[JediFonger]

tor: most BDs utilize ONE .m2t file. this 'stuttering' only happens on my HTPCs, i have two standalone players BD35/BD60 and neither have any issues w/any BDs.

but the HTPCs have issues when the film utilizes multiple .m2t files to faciliate seamless branching. that is multiple cuts of a single film. Watchmen DC is a great example of that.

that is why i want other people to test it out on their own PC rigs, i'm v. curious, my friend has as LG BDROM too but he tells me it doesn't stutter at that point... or maybe he doesn't notice it =P

Which is why you should try different media player applications. Some players may be clever enough to start reading the second file into the buffer before the first file ends, whereas poorly engineered apps may start buffering the second file only after the first one has ended, creating a discontinuity at the switchover point.

[JediFonger]

yeah i've used them all . TMT, WinDVD, PDVD, all same results. that is why i need OTHERS to actually run this test for me =P. if i could isolate somn that'd help.

Hello Jedifonder. I have PowerDVD(7.0 Series) that came with my LG GGC-H20L drive. I have the current 1.03 firmware. In addition, I am using Windows XP(Service Pack 3), MSI G31 and E3200(2.4Ghz overclocked to 3.0Ghz on stock cooling at 32 degrees), updated 9800GT drivers all the time, 2Gb of memory, and have Arcsoft Total Media Theater Platinum with the latest patches installed. I have The Watchmen and I am not having one problem whatsoever when playing this movie with TMT3 Platinum at all. In addition, is your virus scanner running in the background? Have you ran a spyware program to see if this is clogging up the system? Are you video card drivers up-to-date? Are your sound card drivers up-to-date? What OS are you using? Some people are still having a ton of problems with Widows Vista and Windows 7 as far as blu-ray and another high definition format I won't name at this time I advocate hugely. What are the specs of your system? What's the resolution you're running at? Just curious.

Nice set-up on all of these systems. Vista, Vista, Vista. I have the 9.11 drivers as well. You are fine, but I wonder about Vista though. You can have everything up-to-date with a fresh install. I think you might want to read through these forums as well because there are tons of people that had so many problems with blu-ray and HD-DVD playback in Vista. I don't care if it's 32bit or 64bit. Some people say uninstalling PowerDVD and then re-installing it is one fix for some. I haven't used PowerDVD 9. That makes more sense now. Many people still say that the 7.0 build for PowerDVD is still the best out there if you can get your hands on a copy. Lastly, look up all of my post, as I did a mini step-by-step guide to the patches and builds for the 7.0 version of PowerDVD a while back.

Hendra said that he/she is not having any problems with the 7.0 build. In addition, the GGC LG drive like mine came packaged with the 7.0 build when I purchased it from Fry's. Try the 7.0 build.

[JediFonger]

powerdvd is what i own, but i've tried tmt, windvd, MPC-HC, etc. nothing worx to resolve this.

now when you play it back for me, make sure you goto where the 2 files converge, the stutter is actually very subtle that if you do not pay attn REALLY closely you will miss it, it's around that time mark
