those 2 are a pain in the ass.
Search for virtual dub 1.3C it can convert wmv files(some of them anyways)
Or use Sony's Movie convert at the highest Setting on everything and convert them to mp4 that way then convert the mp4 back to a avi then do the process. I know its a pain in the ass but Sony's convert just makes files outargiously to large with no quality.
www.dvdrhelp.com has tons of guides on converting almost anything to anything.
