Everything I have tried so far works.
What does not
The install instructions I followed recommended remove the dll's for
media devices (ipod, MMS, etc.) so obviously they don't work as such,
and I assume those instructions were given because they would cause
issues if left there.
I must say I have not tried many features as it was so slow and graphically so jumpy and sluggish that I personally found it unusable. Even starting it takes so long to show the splash screen that the first time I tried I ended up trying three more times thinking it had failed.
I like MM a lot. It was my one and only audio manager/player on Windows (for the past three years or more) and I was keen to run it on Linux. With the sluggishness etc. I think I will have to pass for now.
UPDATE: It seems that after running MM a few times its performance is improving. I have no explanation as to why. It is now far more usable than it was right after installing it earlier today.
What was not tested
MM has a lot of features, so I can not report on exactly which do and don't work. I found the performance issues too much to bother trying everything out.
Additional Comments
This system is a laptop: compaq nx7010 with 2GB ram, Radion 9200, Intel Centrino processor. Perhaps a newer and more powerful machine would handle MM on Wine better.
