I report this problem, appeared on 2.9b4 version (previous versions all ok): when EMM reads files from cd it freeze for a lot of minutes. Only after this couple of time it gives a good result. This happens with all CD (different brands) and with all kind of codecs. I've tryed with two different drives: anyone doesn't work (Cd doesn't run) during reading process.
The simpliest solution is ever the better one...but not ever the first applied...!!!!!! Sorry Alessio: the "problem" was just the MD5 hash key, I didnt watch there! Thanks a lot! Good work, Arden
