I dont mind the extra work, I learn so much in the process but you are right in that it would be nice to just click and listen. I did check the files were ok using media player classic and BS player as well. In WMP 10 you can tell which files it isnt reading because it shows a zero file size even tho at source the files are of normal (5-8mb) size. Thats the best way of telling if its true corruption or a wmp error.
