INFO: GUI format 1280x720 1280x720 @ 60.00 - Full Screen
It does not matter what frontrow says or is setup for. ATV1(osx) under XBMC is 720p display max. This has been discussed many times in the past.
@davilla Thanks for you quick response !
So is your article Broadcom Crystal HD, It`s Magic. perhaps just a little bit misleading then ?
Especially when you say:

Quote:Question: Will the Apple TV playback 1080p videos encoded with the H.264 codec (like Blu-ray rips)?[INDENT]Are you saying I actually need the BCM970012 to make it work at 1080p on the AppleTV 1,1 or only under a Unbutu Linux installation ? I'm trying to search all the articles but there is a lot of content and long conflicted threads out there and its difficult to find concise info in the noise...
Answer: Yes, the latest version of XBMC (version 10 'Dharma') allows Apple TV to play HD H.264 encoded videos however the original Apple TV hardware is only capable of decoding 720p videos. To watch 1080 HD videos the Broadcom Crystal HD card must be installed into Apple TV along with the corresponding driver.
If not we perhaps should fix the article...just to ensure that new users expectations are set properly, with out having to find all that discussion. I may have spent some cash and a whole ton of time for nothing.....why go down this route to play 1080p content if its not actually supported.[/INDENT]
On the off chance that I've entirely misunderstood you, how do I get my MKV files (from MakeMKV) to play smoothly, with no drop outs and have the audio pass though correctly ?
Again, you dedication to answering question is terrific, and a supported platform gathers adoption.

No, not misleading at all, that's running atv(linux) and there one CAN do 1080p display.
Notice that I always and have always differentiated the difference between display and decode resolution as they are very different things. You CAN play 1080p videos as they will be DECODED but DISPLAY is another issue that has nothing to do with CrystalHD decode.
So far, I see a common factor being VC1 and E-AC-3, perhaps time to try some h264 ?

Being the reader, I'd beg to differ, I'd at least tweak the caption on the Picture to say "The Dark Knight vc1 running at 1080p on an AppleTV (running linux)" ...but now that I know, I'll look at giving it a go....It's probably getting a ways above my comfort zone...
Is it safe to use these instruction for a Linux setup ?
A couple of Q's:
- Is my best bet to configure a "spare" disk and just swap it out with the one in the AppleTV ?
- Do I detect that there is no SPDIF support for digital audio output, and I'd need a separate hardware device to pull out the audio from the HDMI ? If I need to do anything specific to get this to work, and pointers greatly appreciated.
Thanks Again !

@Davilla, per my previous point, from a mac user perspective, we only really have MakeMKV as our first Bluray ripping tool, and depending on the source that may have VC-1 encoding or otherwise, and re-encoding to h264, will reduce quality, and makes it more of a challenge and choice for user adoption.
Other folks (such as @icedtrip) seem to think the issue is with the container (MKV) but I've not got any evidence to prove that anything works just now even at 720p, as it's all choppy or no video.
So identifying the real issues with previously attached clips may help ?
Please let us know if you need any more info ?
Thanks

Try as I might to follow the HOW-TO install a Miminal Ubuntu and XBMC with sound over HDMI on the AppleTV instructions, it seems that I had to use ifconfig to set the ATV IP address manually (I can ping it), but when I try an telnet per the instructions I get a connection refused ?
Not sure where to ask so all help greatly appreciated....I'll get there, with hopefully only a few prompts as I'm pretty persistent and in most cases Google is my friend. :-)

@Davilla
As Observer mentioned, these are direct rips from Blurays or HD-DVDs. Re-encoding into h264 is far from ideal and very time consuming, plus we know that the CrystalHD can handle full quality VC1 videos with no problems, its only those in MKV containers that are problematic.
I also made a few clips having ripped out all E-AC-3 audio and then some with ALL audio ripped out. I still have the exact same issues, so it doesn't appear to be a VC1 / E-AC-3 combo issue.
Again, if I use an m2ts container, the file plays back just fine with all audio intact. This too is less than ideal, because the method I have been using causes me to lose my subtitle and chapter tracks.

Am I right in thinking the latest Nightly Builds don't have Crystal HD Support ?
I blindly updated assuming it would still be supported, having not seen anything to the contrary.
- davilla - 2011-04-03 03:00
should be supported. I'll check.

Video does work normally if crystal hd is disabled. If enabled it shows but it is slow, full of artifacts and jerky, so it is not watchable.
UPS this is card 70012 just for info.

P.S.:
The same video is also not working on ATV2 in neither way (not if hardware acceleration is enabled and also not if disabled).
VC1 not working - defiler - 2011-04-03 12:17
I'm seeing a few people having trouble with VC1 BluRay rips, and I'm one of them
I'm running an AppleTV, with Sam's new Crystalbuntu image. My CrystalHD card is probably a year old now, so this will be the 70012. H264 works a treat - no issues at all. VC1 flickers between the menu screen and black - not updating at all. The sound plays fine.
Before I get into logfiles and such, let's start with the basics:
Will CrystalHD decode VC1 video correctly?
Will CrystalHD in an AppleTV running Linux decode VC1 correctly?
Will the 70012 cards do this, or does it need to be a later card?
Edit: Something of a corollary to the above, does XBMC 10.1 support VC1?
Recoding to H264 is not always an option - I can't get subtitles to work properly with the tools I have, so forced subs are gone. So should this work?
