LAME ACM MP3 Codec 3.99.5

This codec caused an error when used in virtual dub VCR. There was an "access violation" error when I selected "compression" from the "audio" pull down menu. The error does not appear now that I have uninstalled the LAME codec. This is dissapointing because I lke the LAME codec, and I use it for audiograbber.
