Anyone have any ideas?
I had the same problem.
From the research I did, you have two options:
1) Replace the bsdtar that was shipped with MapConverter with a newer version, which seems not to crash, or
2) do not use compression in MapConverter (this is the method I chose, as I didn't much feel like spending the evening hunting down bsdtar just so I could save a bit of space creating a tar'd, gzip'd copy of the data that had already been converted -- which is what bsdtar does. ".tgz" is a common Unix filename extension indicating that a directory has been run through the tar utility, and subsequently compressed using gzip. And that's bsdtar's function.)
Of course, if you go with #2, you'll discover that Windows doesn't natively support burning files to DVD the way it does with CD, and you'll have to use a third-party application to do this.
Alternately, if you have a 4GB USB flash drive, you could just copy the uncompressed directories over to it, and then copy them from it to the Mac. I believe you can pick up 4GB flash drives for about $20 these days.
