I am using Windows XP SP2 with the latest DMC Beta release. I was converting a few large files (each above 120 Mb) from WMA Lossless to LAME alt preset standard and I found that two of them were cut before the end. One of them (and perhaps the other one) was showing the right length in Winamp though. I then converted the same WMA again to LAME (same settings) and it worked.
