TSSplitter

TSSplitter is intended for splitting and joining large MPEG Transport Streams containing any kind of stream encoding, including MPEG2 and H.264 (*), to burn them to DVD. The advantage compared to other similar tools is that you can later join the files and get a file that's 100% like the original source file, so you get no klicks or image glitches on the join position, and you can for example re-seed the file via BitTorrent.

TSSplitter also lets you preview the beginning and ending of each partial file, so you can check that the file is not split in the middle of a sentence. You can select from different naming schemes for the partial files or make your own scheme.
