Cut M2V file into several parts

[nonoitall]

I'm encoding some TV episodes to be put on DVD using HCenc. I'm putting multiple episodes onto a single disc, so in order to distribute the available space intelligently, I encode all of the episodes as a single, long video stream, but I mark the frame numbers of each episode break as a chapter in HCenc (to ensure that each episode starts with an I frame). Now I have my long, multi-episode M2V stream, and I want to split it up so I have one clip for each episode. This seems like it would be a common task, but all my fruitless Googling and searching for a solution indicates that the opposite is evidently true. So, how do we split up M2V files at given points (assuming each segment has already been tailored to begin with an I frame)?

Have you tried mpg2cut2?

You can select clips exactly and add them to the clips list(+ button), and last save all clips(file save clips). But the gui is not that simple, hover your mouse over the buttons to see what they all do.

That looks like it will do the trick. Thanks!
