VideoRedo plus will edit and split files and convert them to quite a few different formats. I edit and convert all my HDTV .TP caps from my HDTV card with it then after that I run the Mpeg it makes through TSMuxer to make the AVCHD files in it's own folder that I can then burn directly to DVD with ImageBurn.
The trick is to cut the files down small enough to fit one DVD then maybe make a second folder with part 2 if the original file is too big to fit one disk, or use DL disks.
VideoRedo isn't free but they offer a trial version if you want to test drive it and see if it works OK for you. http://www.videoredo.com/en/Download.htm?download=plus
they have a forum and web site as well. I'll have to see if it supports your format, I usually do .TP with it and I think it does a few others as well.
