HI.

I have two blu-ray rips, Transformers 2 and Half-blood Prince. Both ripped with MakeMKV. Neither one plays well on the wdtv. They start off OK, but then the video gets choppy, and the audio drops out. Specs are below. All my HD-DVD rips play fine

I am running b-rad 0.5.8.1 on the WDTV.

I also tried running the MKV thru tsmuxer, and the resulting M2TS did not play at all on the WDTV.

Any ideas?

Thanks,
John

The files look ok. 

Are you playing them directly off your hard drive?

WDTV LIVE with current official FW > HDMI > DVDO > Sony CRT Projector 150" 16/9 screen.  Toslink audio to Yamaha DTS receiver. No Network set up yet.

I'm playing them over NFS. Everything else I have plays fine over NFS, including HD-DVD rips at 1080p.

I'm in the process of copying the BR using anydvd, and then eac3to to see if that makes a difference, since I used eac3to to MKV-ize my HD-DVDs. I don't think it would make a difference, but I figure what the heck.

Should NFS make a difference? I could see how network speed issues might affect the whole thing (video and audio), causing it to stutter or be choppy. But why would NFS for some reason chop the video and kill the sound? 100base network, no other network traffic at time of playing.

Sounds like your network is probably the bottleneck here...

Only way to tell is to copy these to a USB drive and see if that works... if it works fine off USB connected drive, then it's almost definitely a network issue.

I'll give that a shot and get back to you. Probably won't be able to try until tomorrow evening.

This is your problem

"Overall bit rate                 : 37.3 Mbps"

This should play fine in a usb attached hdd,but the network might give you troubles (if network is not optimized)

The other file
"Overall bit rate                 : 20.1 Mbps"
might play better,but still a toll on a network.

For sure,you could optimize your lan and get better results.

So, assuming LAN issues.....any tips or hints for network optimization? Limited to 100base because of the USB network adapter (do they even make 1000 USB network adapters?....maybe a trip to newegg is in order).

I already have switches (no hubs), cat 5e cable. Computers are all Mandriva (2009.1 & 2010.0). NFS. Would a direct line between server and wdtv help? (Tho it'd mean a second NIC in the server, no? and i've never played with that before.)

I do have a full box of CAT6 if you think it'd help. :)

Have you considered sacrificing some quality and re-encoding these to a lower bit rate MKV, like in the 8000 to 9000 kbps range?  If that's an option maybe check the bitrate on some other 1080P encodes you have that play well over your LAN, and re-encode these to that same spec...  takes time, but will save you a lot of hard drive space.

Yes, plenty of Gigabit USB 2.0 Network adapters to be had. I'm useing one myself. Don't ask me about streaming, though. I'm just useing it for file transfer from the PC to the HDD on the WDTV usb port. This way your only choke point is USB 2.0. And there's certainly no streaming issues that way. Takes a bit of the guesswork out of troubleshooting.

Conversely, what's a good way to reduce the bitrate without any noticable quality loss? Handbrake? Had troubles with that and H264-ing some DVDs. Probably just needed to get the settings right, but got sick of trying all kinds of options.

And, they did all play fine locally. Oddly, even the M2TS, which was an recognized format when I tried playing it over NFS.

thanks,

p.s. I'm running linux (Mandriva 2010.0 x64) so any programs I'd prefer run natively in that. Tho I do have a 32bit WinXp VirtualBox I can pull up as well if need be. I also have a 32bit Mandriva VM for S&G.

What NFS send/receive window sizes are you using?  You could try some different settings to see if that makes any difference.  Have you done any speed tests over the network?

Download any of the mkv's available in the net to make your tests,none of them use brutal bitrate like your rips.
The suggestions are good : when you rip,and you mean to play those through the lan ( not directly from hdd),you should re-encode to lower bitrate.
Quality will be lower,but not very noticeable,plus,you can see which one suit better your needs.

See all the reports from people that say 1080p cannot be streamed : this is why,to high a bitrate.(chokes the network)

Unfortunately I don't know of any Linux tools, as I'm a windows guy... but I really like ripbot264.

You will need to install Ripbot264, ffdshow, haali media splitter, and .net Framework.

I usually just use 2 pass encode, and select the bit rate manually...  you can tweak settings like reframes, crop black bars from the top and bottom (if the video has them you can get rid of them), output size, etc.

http://www.videohelp.com/tools/RipBot264#guides

Word of warning, converting to MKV takes a long time, so unless you have a fairly powerful machine let it run overnight... or while you are at work...  also since you are running virtualized windows, this is probably going to be really taxing on your system to essentially be running two OS' at the same time as the conversion is taking place.

Well, I'm running thru handbrake, trying the first two chapters of half-blood prince, at CQ's of 10,12,14,16,18. They should all be done by tonite at some point, and I'll try them all out tomorrow probably.

I'm running Transformers2 thru handbrake right now, CQ=20, 4 refframes, all other settings left at default for High Profile, saving to MKV...and I CAN notice a difference. Seems to be playing back alright, except.....

I can't notice it so much on brighter scenes, but definately on darker scenes and black screens, I am seeing a lot of artifacts. And that's exactly what I'm trying to avoid. It's a large part of the reason I've left all my DVD's as plain rips from MakeMKV and have not run them thru any compression.

Are there some other settings I can adjust to maybe get rid of those artifacts, or at least most of them?

As far as the network goes, send/receive window sizes are both 32k, UDP (tho I tried TCP as well with no difference). Trying to set 64k on the WDTV reset back to 32k. The other nfs testing tools don't seem to be included with the nfs app pack. Also, all my switches and NICs are 100Mb, so a USB-Gig adapted wouldn't make all that much difference.

thanks,
john
