Well that's what I thought might be the case, but I'm not a lawyer so I can't say for sure. I suspect it depends on whether they have a patent on the file format. Microsoft did go after the guy that wrote virtualdub who made an importer for ASF format, but that is a format designed for copy protection, so maybe they went in under the DMCA for that.
If it was me, I'd just go for it, and worry about the consequences later. :-) Worst likely case is that they send you a cease and desist and you have to stop. Actually suing people costs a lot of money.
