Some people reported problems with the LAME DLL. It works flawless for me, so those should try to redownload it. Albert Faber just released a bugfixed LAME DLL with his CDex 1.20, download it and try that DLL. If it does still not work, please contact me again.
The problems on SCSI bus reset during writing are still unsolved, I just removed the SCSI1HLP.VXD from my windows/system/iosubsys directory, I hope this would help somehow.
