VideoRedo is working on H.264 ts files but don't know time frame. People have been pushing them for two years! I installed the latest beta and when I tried to import a .ts file, I got a message that it wasn't able to edit H.264 files yet. So this looks encouraging.
My Nero Vision 6 can import our files and it will write a dvd to hdd. The resulting vob file will import into VideoRedo and can be edited and output as a mpeg2 file (with sound!).
