I'm looking for a free tool to cut MPEG's that are created by recording from a USB cable receiver.

There are a number of applications that do this, and some are free, but most of them take the video and audio decoded and pass them into a codec again to write the final output.

I already have the MPEG's encoded the way I like, so what I need is a tool that can strip the beginning and the ending of the recording before and optionally commercial breaks, by rearranging the data within the file, not re-encoding it.

Now I'm using some old software that came with the cable-receiver, but this actually re-encodes the video when exporting. I've tried VirtualDub but had major trouble getting the audio and video streams to stay in sync (and this was also re-encoding)...

I found this which comes pretty close, but doesn't allow much accuracy in selecting cut positions.

By far, IMHO, the best thing to use for cutting video snips is the COMPLETELY FREEWARE AviDemux for Windows.

If you know where the slicing is to be done,
these split and trim questions should help.

Quicktime Pro can do this, although it is not really free.

Maybe give MPEG Streamclip a whirl? I think it'll do what you're looking for, though I've never used it.
