My question is how to Join Panasonic HDC-TM700 with Raw MTS Output for MythTV?

If you have MythTV as the digital video recorder (DVR) for capturing unencrypted HDTV stream or home entertainment software, you may find it a great partner for home theater. The internal player of MythTV supports playing Blu-ray disc. While you can play .mts or .m2ts files with MythTV internal player, you may also like to cut the unwanted part to keep the useful segment, or merge related video footage to one large file before putting the videos to MythVideo directory.



Since the source AVCHD files from Panasonic HDC-TM700 camcorder are generally in high quality, it would be perfect to get raw mts or m2ts output

But how can I join Panasonic HDC-TM700 output with Raw MTS Output from MythTV or other source without re-encoding? I know that I need to use HDWriter from Panasonic to get the video from my camcorder, since otherwise I will have audio and video out of sync. Then I wonder whether Pinnacle Studio, Adobe Premierre, Sony Vegas or any other high quality editor will be able to edit, cut and split my video losslessly. The only thing I have found is a low quality tool that spammers mention in every forum and blog.
