Thanks for posting the info on converting mkv to AVCHD format. I recall the last time I tried to do something similar I was using Toast for Mac OS X. It seemed like there was some transcoding going on and I ended up cancelling it as it was taking way too long. Should that normally happen? I know .mkv is not a native BD format, so I suppose some type of conversion will be necessary, but how long are talking here to produce a disc? Shouldn't burn time be the longest part of the process??

The point of AVCHD is for it to fit on a DVD9 (7.9GB), so seeing as the video track in the mkv is 12GB, you have to transcode to get it to fit a DVD9. If you're serious about keeping the picture quality high, you need to use a slow setting and this can then take anywhere between 6 hours and several days depending on your CPU, RAM and HDD speed. If I remember correctly, it took me something like 18hrs to encode the AVCHD and 36 hours to encode the BD.
