Don't think atv2 has the ponies for 720p60. I'll continue to investigate over time.

[KidMirage]

Thanks for looking into this davilla. The thing that confuses me about these 60fps samples is that the video and audio both seem to play OK, just way out of sync. It's hard to tell, but the bad sync doesn't seem to vary over time.

I'll be posting my logs today. I had to get another blue ray quality rip on my ATV 2 as my wife deleted the ore way.

Now I'm curious about something. Since everyone is saying the mkv h264 will play on my apple tv 2 what would happen if I converted a high definition video to the mkv h264? Would it still be high definition 720p and then it should play correctly then.

My thought is I want to take the file that started this all which is the high definition version of e social network from icefilms and use handbrake to covert it.

Now I also downloaded handbrake and I was a little confused. In the preset menu do I need to choose apple tv 2 since that is what I'll be playi it on correct? Then I just need to change it from mp4 to mkv and start the process right? Any other changes to the settings I should make.

I tried this with one of the .tp files I had recorded with my HD-PVR. I converted the file to .mkv which didn't involve any transcoding, just changed the containers and the result was the same (audio way out of sync with video). I took the same file and transcoded it to 30fps and it worked fine.

When I get home I'll try it first since the file I want to change is a avi. If it doesn't work I'll try the 30fps thing. I'll report back later.

Here is the odd thing though. If I stream the HD 720 content from Icefilms it will play fine on my atv 2 although it will buffer like crazy yet when its downloaded and I try to play it I get the lags and skips. This is so annoying lol

If you just converted the container to mkv then the video wouldn't be h264 it would still be the original mpeg2 codec that the transport stream used and hence no hardware accelleration

mkv is just a container that you put video and audio stream into, you need to convert the video stream to h264.

Sorry I wasn't clear. The HD-PVR does produce H.264 video. By default the files are created with a .tp extension. I typically use VideoReDo to clean up the files a bit and it changes the extension to .ts. It's definitely H.264 though. Here is a Media Info listing:

this is not h.264 ... its avc 720p 60fps ... no hardware acceleration for it ...

[exiledone1]

Now I also downloaded handbrake and I was a little confused.

In the preset menu do I need to choose apple tv 2 since that is what I'll be playing it on correct?

Then I just need to change it from mp4 to mkv and start the process right? Any other changes to the settings I should make to turn my HD 720p movie into one that will play on the ATV 2?

Pretty new to converter software and stuff so just not sure about the correct settings.

[KidMirage]

From what I have read there is not much if any difference between AVC and H.264, in fact AVC is one of H.264's "family of standards". (See H.264/MPEG-4 AVC.)

These files play without problems with XBMC (Dharma) on my Acer Revo 1600 at very low CPU levels which tell me they are being accelerated just fine. In fact the video seems to play fine on the ATV2, no stuttering or skips, again with relatively low CPU (around 60%), they are just out of sync with the audio.

Okay...I installed Handbreak and tried to convert the Social Network HD MKV using h.264 video codec. I don't know how to use the program so I just choose the Apple TV 2 preset. I would love if someone could tell me the setting they use to produce mkv files that play on XBMC on the ATV 2. I didn't change any of the settings, even though it seems there are tons.

The end results were a nice video, but sound was off. It had a odd almost echo sounding effect. Not good at all. The file started off as a Avi and I was converting it MKV. Can someone tell me what when wrong. here is the mediainfo for the file I was trying to convert:

ATV2 profile should be fine, by default i think that profile will create two audia streams 1, is two channel AAC, second stream is AC3 passthrough

Do you have 2 streams and can you select and listen to the second stream fine?

[exiledone1]

I'm not sure. I don't know much about that. I'll have to check. Why would you need two audio streams? Isn't one enough? I guss I don't understand the purpose of the two different streams

[chuckles]

Cant answer that one sorry, I personally don't use it (handbrake + atv2 profile) and are just going on my handbrake default profile setup here.

You can play with the profile and just set it to use a single ac3 pass through stream
