BD / AVCHD differences
Question for those who have ventured into the HD realm. I've begun creating edits in HD. I released my Because You Were Home edit as a 1080p MKV. It was quite easy to make the MKV, but I thought I should also offer it as an AVCHD disc. I can easily make a no frills disc using tsMuxer, but it would be really nice to have menus. And this is where I am starting to run into problems.
DVD Architect 5+ can create Blu-ray discs, however I have read that there are some differences between AVCHD discs and Blu-ray discs burned onto a DVD5or9. I don't want to go to the trouble of creating a BD disc if it is incompatible on people's players. Can anyone shed some light on this?
SO, if there are differences, what methods have people used to create an AVCHD disc with menus? I have tried multiAVCHD, and I can not get any version of the software to function properly on my system (Win7 64-bit). I have heard that DVD Lab Pro can do this, but I didn't see the capability (though I confess I don't know much about the software, as I am an Architect user).
If I'm stuck creating menu-less AVCHDs, I probably wont upload one for Because You Were Home, but rather just post simple instructions on how to take the MKV and create an AVCHD disc (using mkvExtract, and tsMuxer), and for worthy future projects I might just create a full fledge Blu-ray version (like for T2).
DVD Lab Pro can make AVCHD discs? I did not know this because I use this program. I'll have to look into this. Thanks Throw!
Don't quote me on that. I don't know. I just saw a couple other people post about this capability, but I didn't actually see it myself when I took another recent look at Lab Pro (just saw DVD options). Would be good to get a knowledgeable answer, and if it is possible, some quick notes on how to do it.

I've been using multiAVCHD longer and have learned to live with its quirks and can use it fairly effectively these days. I keep meaning to write up a guide for it, but then things get in the way. I think my latest edit, Alien 2 (due out next week), turned out well.
thanks thunderclap. I have heard that multiAVCHD is great stuff (yet buggy), but I can't get it to function on my system. It kept crashing (no matter what version I used).
Do you happen to know what the actual differences are between an AVCHD disc and a blu-ray disc (even if both are on a DVD9)?
How would a blu-ray disc go on a DVD9?

AVCHD can support two audio formats: AC-3 (at up to 640kbps) and PCM. Other audio types might work on your player but are out of spec AFAIK. AVCHD is widely supported by stand alone players. I think support is virtually universal in recently released BD players.
BD-9 and (unofficial) BD-5 can support other more advanced audio formats, but are far less widely supported by stand alone players. For fanediting, there is no reason whatsoever why you would need to use more advanced audio codecs and so no reason whatsoever why you would need to go with BD-9 over the far more widely supported AVCHD.
Give AVCHDCoder a look. I haven't used it yet, but it looks promising. I don't like multiAVCHD -- much as I'd like to -- because of its compatibility problems and bugs. I don't like the interface either: it seems, well, cluttered.
A BD structure can go on a DVD-9. A disc is just a storage medium. You just have to make a player that can read that structure from that medium.

as Captain explains in his post, its basically a BD structure with a bitrate low enough to fit on a DVD9. I guess I should have been more explicit and said BD-structure on a DVD9 (aka BD9)

I was led to believe there were differences, but couldn't actually find what they were. To rephrase, I should say if you author a BD9 disc with AC3 audio (at say, 448kbps), is it any different than authoring an AVCHD disc?
Just taking a quick look at the screenshots for AVCHDCoder, it doesn't look like it has menu support. It's easy to create a movie only AVCHD disc using tsMuxer, but I am more interested in one with menus.
The answer is yes, but I cannot give you an in depth technical explanation of the differences. One is that strict AVCHD does not have a Certificate folder and BD-9 does, I believe. (AVCHD AUX does.)

Thanks Captain. It would be really good if we could figure out the differences. If it is just the presence or not of a certificate folder, in theory you could make a BD9 AVCHD compliant. ...but somehow I am guessing there is more to it than that.
