at 6Mb/s it seems that an average HD can easily support 5 streams to 5 ATVs.
With a seek time of 10ms lets say it would spend 50ms per second switchng between the different movies and have 950ms to transfer the content. Just looked at a LaCie drive. It states 480 Mb/s transfer rates via USB2.

Has anybody got experience with multiple streams in 720p from a server set-up using ATVs to deliver to the TV?
 
Your bottleneck is delivery to the Apple TV(s) (i.e., wifi or ethernet).

OK so HD is not the slowest part in the chain but the connection.
Lets say I use a mac mini as the server and chain the ATV via ethernet will that have enough capacity? 100 in ethernet terms refers to 100Mb/s so that should be plenty if about 30Mb/s is needed, right?

Anybody actually tried this out with more than one ATV in 720p? What is the most streams anybody tried out?

Thanks for help, this is a great forum!

Edit: Question answered. 5 video streams & 5 APE streams seem possible

if the airport expresses are gigabit, then the limit would be more like 300mbytes/s, but i dont think they are yet. an extreme would do it though..

i dont think they had all of their movies at 720p. when i watch a 720p movie over my network the needed bandwidth is somewhere around 3-4mbytes/s, so having 5 playing HD content at the same time would start to push the mini's slow HD. very good to see though :)
 
Unfortunately, the ATV is only 100 mbps by ethernet. There goes Apple again...

aaahhh ok then that makes sense. i guess apple werent too worried because you can only stream 1 movie at a time to the ATV, so a 30mbps movie is going to be pretty darn good quality haha.

syncing would be time-staking though!
 
Cave Man, is there anyway in Handbrake to encode the m2ts in full 720p? In other words, go from 1920x1080 to 1280x720 vs 1280xwhatever?
 
FYI, a new version of AnyDVD HD was released a day or two ago that can handle the latest version of BD+ found on some newer discs. They had estimated it wouldn't be ready until February; either they were being very conservative or had a major breakthrough.
 
No I guess what I'm asking is if a Blu-ray is 1920x1080 that is 16:9. But when using the AppleTV preset, then adjusting Picture Settings to 1280x528 (Keep Aspect Ratio), 1280x528 is not 16:9. So if I uncheck "Keep Aspect Ratio" and set the output to 1280x720 will it look funky? It should remove the black bars.

1280x528 is the frame minus the black bars. There is no need to waste bits on the black bars as the playback device will display it properly. You're trying to overthink things... just use the preset as it is (although I would recommend lowering the CQ% to 55-57; the preset was designed with DVD sources in mind).

I'm not trying to over think anything. I'm simply trying to understand why converting a 1080p Blu-ray to "720p" (using the preset) results in a 1280x528 file that when played on the AppleTV shows black bars on the top and bottom. Doesn't make sense to me since 1280x528 isn't 16:9. Unless I'm missing something here.
 
Not all movies have the native aspect ratio of 1.78:1 (aka 16/9, 1280x720). A movie with an aspect ratio of 2.35:1 (or wider) would have a smaller horizontal resolution because Handbrake crops to fit the size of the picture. This is why you will see resolutions like 1280x528.

So basically its widescreen?
 
This is my first attempt so bear with me. I'm trying to encode National Treasure 2.

Handbrake (on either Mac or Windows) doesn't seem to like the stripped down m2ts file that I created using TSmuxer. So I resorted to using the original m2ts file from the rip.

Handbrake reads the file except it can't encode the LPCM audio track. Oddly enough, that's the only track that's in English.

I am able to encode the video with french, spanish, director's commentary etc but not english (because they are all AC3, not LPCM).

What to do now?

I had the same problem with Superbad. I ripped it again with AnyDVD HD and it worked. I'm also using svn local builds of Handbrake, too.
 
If I remember correctly, there were some improvements made in the way Handbrake handles TrueHD audio tracks AFTER .9.3 was released. You can compile from SVN development code, or wait for the next developer snapshot release.
 
I've noticed some improvements from the svn builds. But I'm still getting hangs on "I, Robot" while scanning previews (whatever that means).

In my experience with down-converted TrueHD->AC3 titles (all using TSmuxer).. Handbrake does recognize and encode them.. but it takes it a very long time to scan the files, somewhere around 30-45 minutes. Just start Handbrake and go do something else, and you will see it will eventually accept the title. I am using released 0.93 version.
