hi, i don't know if this will help but i also get disk problem errors occasionally and i just thought i'd share with you what i did last time (today in fact!)

the file got to 100% but was saying disk problem (of course!) so i went to 'explore' and it took me to the incomplete folder where it was stored. the file was there- i had to extract the RAR files and i just cut the extracted avi file and put it in another folder- i then deleted the 'incomplete' file (which was actually complete!) and cancelled it from limewire. the avi file plays perfectly (haven't tried burning yet) i think even if the 'incomplete' file had already contained an avi or wma or mp3 file that i could still have cut/paste to another folder and it would have played so maybe try that? unless you're getting the error message at 2% complete in which case it won't!

hope that helps!
