Well, I never made an mkv of ESB and ROTJ, so you downlaoded something weird. How big are they? If they are the same streams as the AVCHD just remuxed to mkv, you could probably use MKV Toolnix along with MKVextract to extract the streams from the mkv and then use TS Muxer to remux to AVCHD.

Anyway, here's something new:

I could try to use those programs but I would rather just mux the original AVCHDs since I don't know if this weird MKV that I have is curropted in other ways. By the way would it be better if I asked you my questions in a Private Message as you can probably tell I am very much a novice at this
