There defintely seems to be a bug using AVCHD clips in CS6. The multicam with spanned clips is unusable in a superfast 6 core processor with the latest nvidia card also the exports show corrupted footage and red frames occasionally. Single line spanned AVCHD is also a problem with red frames showing up. The camera I use is a Panansonic HMC-150 but I use Premiere this on a daily basis so I had to go back to CS5 where everything is working fine on the same computer and hardware setup. I guess shame on me for upgrading too fast but it's almost like releasing a version in the early 2000's that doesn't work with DV. Strange.
Oh and why not add a feature to have your timeline export Mpeg DVD to fit a dvd? If you export to DVD just have a fit to single or dual layer DVD option instead of having to fool around with the bitrate every time you export. The sizes of the media are not a mystery and I would bet most of the time people are exporting and just want to max out the DVD space. This feature used to be in CS2 i think I remember but was taken out. Strange.
Yes, there is a CS6 Bug AVCHD http://forums.adobe.com/thread/1004369?tstart=0
Exporting from PPro as MPEG2-DVD means you do the math
If you want Encore to use automatic transcoding to make a "best fit" you need to export from PPro as DV AVI
>feature used to be in CS2
PPro 2 had a limited "direct" DVD authoring capability, so you made the DVD right from the PPro2 timeline, with no exporting
That direct to DVD capability was removed with CS3, so you either do the math yourself or export as DV AVI for Encore to do the math for you
