The 6.1 channel order is chosen on a simple thing: The channel order HDMI devices expect. With the channel order implied by 0x70f, HDMI receivers will assign channels to the wrong speakers, with 0x13f, it will work just fine. At least on my receiver, and i never got complaints otherwise.
So unless you have some real-world problems, skip the theoretical assumptions, and stick to what happens in real devices. PS: If you disable "Convert Output to Standard Channel Layouts" in LAV Audio options, it should give you whatever channel order was stored in the file, without any remapping.

How the hell would it already support them if the only tool that can write them was just released an hour ago? :P
I usually prefer faster seeking over subtitle display myself, though.

So yeah, if you seek in the middle of a sub, you won't get to see it, because i just don't know if there is a subtitle just one data block before, or maybe none at all, or 100mb before ... its impossible to know, now at least. Patches welcome, doubtful i will spend much time on this anytime soon. Not sure how hard that even would be to add, maybe even easy, do it in the high-level code above matroska seek logic, check if there is a Cue point with Time+Duration for a subtitle which falls into your frame, and then adjust the target seek time to that. Don't even have to toy with the low-level seeking. Maybe, just thinking out loud here. If you wanted make working on this easier, you could prepare a sample file which helps to demonstrate the problem which is supposed to be fixed by this (preferably muxed by mkvmerge 5.9.0 so when i try implementing it, it actually helps ) If i don't have to dig around (or even make) for this stuff, it'll make it a lot easier. PS: Keep in mind that i do not use ffmpegs matroska demuxer.

I sent you some simple samples muxed with mkvmerge 5.9.0.
It's probably a bit more complex than that, when you consider overlapping subtitle lines (CueDuration) residing in multiple MKV clusters scattered minutes to hours apart. In order for this to be in any way efficient, you'd want to seek and pull subtitles as directly as possible using CueRelativePosition, while not actually seeking the video or audio at all. Implmenting an intelligent background subtitle cache of some sort, may also be useful for cutting down on potential random access seeks. |

@ Nev
Strange thing happened after today's ffmpeg updates, most likely a false positive (my Avira it's going nuts ? ) but I thought to report this to you : when trying to build a new version of LAV my AV it's saying that "print_options.exe" from ffmpeg/doc/ it's a Trojan?!

Win8 and DVD navigation?
Win8 doesn't include DVD Navigator.
Will Lav support DVD navigation? Or are there any "recommended" alternatives? It would be great to see Lav's (simple) blueray navigation extended to DVDs... Thanks! Lee |

Anyway the point remains that LAV Splitter will never offer any more DVD features, so if you want to play DVDs you better get Windows 8 Pro or the Pro Pack (or you get another DVD player like PowerDVD or the likes)
