i got allmost rid of the long conversiontime by changeing the value "set conversion priority"(dont remember how it's called exactly) in the mast page from "lower" to "higher". it still needs to convert the programs then, but it will convert them a lot faster.
This parameter doesn't seem to exist in the master page as far as I can see?? If you mean the rate cnv setting it is recommended for many libraries to have this set at 3200ms or more.
well, its actually like this: in the taskmanager you can change the priority of a certain program. this parameter does the same for the loadingprocess. if you set it to higher, then all the ressources are going to be used for it. that means you would eventually notice some crackles while audioplayback, but only while the new program is loading. for me this is a fair compromise. but you have to decide for yourselve.
