I can well understand that DivX doesn't support every format that MKV offers. After all MKV basically allows you to stuff any content into itself and its at a players discretion what it decodes. I would hope at least that their "profile" specifies subtitles, chapters and a few bits and pieces in addition to audio.

More interesting is DivX *hasn't* said, concerning the way encrypted movies will be delivered and encrypted. This is where the real money lies. The certification is a trojan horse to get the devices into homes, and then be able to sell them content afterwards. Didn't exactly work with older versions but the brand is stronger now.]]>Jan 14th 2009 5:20AMhttp://hd.engadget.com/2009/01/14/h-264-based-divx-7-makes-landfall/http://hd.engadget.com/2009/01/14/h-264-based-divx-7-makes-landfall/
Unless something out there transcodes AAC to AC-3 or DTS, I can see that being a major block towards it being used for serious downloads.

Or is there a workaround, say, support for an optional AC-3 or DTS audio track?]]>Jan 14th 2009 8:17AMhttp://hd.engadget.com/2009/01/14/h-264-based-divx-7-makes-landfall/http://hd.engadget.com/2009/01/14/h-264-based-divx-7-makes-landfall/
On the PC, as long as DivX 7 is installed, your regular DirectShow player (Windows Media Player, etc) should be able to playback the MKV properly, as Windows already has a AC3/DTS decoder for its built-in DVD playback, and if not, AC3Filter is free. DivX Player isn't much of a player in and of itself anyway.]]>Jan 14th 2009 8:29AMhttp://hd.engadget.com/2009/01/14/h-264-based-divx-7-makes-landfall/http://hd.engadget.com/2009/01/14/h-264-based-divx-7-makes-landfall/
It's not as if the effects of using a poorly supported codec aren't known. The only major criticism I've heard of the Netflix box is that the audio is stereo. Why is it stereo? Because they're using WMA. How many receivers out there support WMA surround sound? Not enough for anyone to feel they can distribute audio in the format and claim, honestly, that they're distributing surround sound. Given that DivX announced DivX7 after the Netflix problems came to the surface, you'd have thought they'd have realized they may have a major problem going with AAC.

I don't want to sound like I'm down on AAC. It's an excellent codec. It's just... well, it has poor hardware support. If you're going to go with that, why bother with AAC? Why not standardize on Ogg Vorbis and FLAC, with Dirac and Tarkin specified as the video codec choices? You don't, of course, because you get the same problems.]]>Jan 14th 2009 9:00AMhttp://hd.engadget.com/2009/01/14/h-264-based-divx-7-makes-landfall/http://hd.engadget.com/2009/01/14/h-264-based-divx-7-makes-landfall/
My guess is that if Breakthru is seeing higher quality H.264 output, then the DivX decoder is somewhat more efficient than the one he's comparing it too, and thus is able to decode at a higher quality for the same CPU power. Or, of course, he's forgotten to turn certain features on, like the loop filter in VLC, as some implementations do not automatically switch on and off the various optional features depending on how much spare CPU they're detecting.]]>Jan 14th 2009 9:09AMhttp://hd.engadget.com/2009/01/14/h-264-based-divx-7-makes-landfall/http://hd.engadget.com/2009/01/14/h-264-based-divx-7-makes-landfall/
I agree about what you say about the audio formats, FLAC, Ogg, AAC, whats it matter if the receivers can't decode it anyway? Well, here's why, bandwidth isn't up to snuff to do more than stereo. That's why its stereo, not the format used. The format used is only the end to the means in terms of DRM. MS has worked very hard to make their format work well for this sort of application.

As for receivers that decode WMA. Probably more than any other non standard format. In fact, it has to be, I dunno of any other format that's supported at any level. If Netflix goes surround, it's probably gonna use that. Then I guess the players can use some sort of on the fly AC-3 re-encoding or something.]]>Jan 14th 2009 9:11AMhttp://hd.engadget.com/2009/01/14/h-264-based-divx-7-makes-landfall/http://hd.engadget.com/2009/01/14/h-264-based-divx-7-makes-landfall/Jan 14th 2009 10:50AMhttp://hd.engadget.com/2009/01/14/h-264-based-divx-7-makes-landfall/http://hd.engadget.com/2009/01/14/h-264-based-divx-7-makes-landfall/
With MPC-HC, CoreAVC, and FFdshow, I think the divx player is pretty useless for PC , unless you want to play divx7 content I suppose.]]>Jan 14th 2009 8:09AMhttp://hd.engadget.com/2009/01/14/h-264-based-divx-7-makes-landfall/http://hd.engadget.com/2009/01/14/h-264-based-divx-7-makes-landfall/http://www.engadgethd.com/2008/12/23/divx-7-gets-january-2009-release-date/

But I will bring up the point that Divx 7 is _as fast_ as CoreAVC, and the decoder is free. Not only that, you can get just the decoder. Most people I see who speak so highly of CoreAVC haven't even paid for it.

No one really cares about however DivX plans to sell movies, especially in this ecosystem. There's just so many more and better options for that. Not only that, there is MPC-HC as solidunit has mentioned, and Windows 7 supports H.264/AAC decoding.

The only real benefit from all this is twofold.......a free decoder that's as fast as CoreAVC, and their DivX Plus Certification will make MKV a standard across many hardware devices. Nothing else really matters and not much else DivX plans to do will get anywhere anyway.]]>Jan 14th 2009 8:20AMhttp://hd.engadget.com/2009/01/14/h-264-based-divx-7-makes-landfall/http://hd.engadget.com/2009/01/14/h-264-based-divx-7-makes-landfall/http://www.divx.com/en/downloads/divx-7-showcase]]>Jan 14th 2009 1:44PMhttp://hd.engadget.com/2009/01/14/h-264-based-divx-7-makes-landfall/http://hd.engadget.com/2009/01/14/h-264-based-divx-7-makes-landfall/..
