A2KMike and Songpony please keep in mind that MTU doesn't write the drive interface code for the program themselves, but get it from a third party vendor. This is not to excuse or dismiss the problem and I know it is still an issue MTU is trying to resolve. Sometimes it takes time to resolve issues like this.
With this last upgrade of Hoster, MTU expanded the number of CD/DVD drives usable even more. Unfortunately, for what ever reason the people who wrote the new MMC coding leftout or changed something in the code that only allows for RAWDAO96 format instead of choosing the correct interface for the drive in question.
MTU is not the only one to do this kind of thing...just look at the things Microsoft does to us!!
And we take it in stride.
Give them some time and hopefully a cure will be found. Mean while if you have room try another non-Plextor for your singer imports, keeping the Plextor to do disc imports.
Admin has been talking about another upgrade before the end of the year, so keep your fingers crossed.
