well, I think no body run into this problem because you guy not used roxio 7.5.
I have roxio 7.5 installed and working good with anydvd, clonedvd2, dvddecrypter, dvdshrink, nero recode,... but not with alcohol 120, it is conflict with upperfilter and lowerfiter set by:
lowerfilter = anydvd elbydelay cdr4_2k
upperfilter = cdralw2k pwd_2k
if I removed these 2key than alcohol 120 will enable read speed to maximum and I can select the read speed I want when ripping dvd.
Anybody have other way to work around this problem because I don't want to remove this 2 key cause other application not working.
Or I just uninstall alcohol 120 and not use it.
