I got a new F90Bt and love it. I just have a few questions. I can't get it to play burned DVD's in any format. I have the 2.0 upgrade but still can't get it to play the DVD's. It plays store bought DVD's fine. Also every time I power the unit up it says updating VR Dictionary for about 2-3 minutes. Just curious if this is normal and if you can get it to stop doing this. I have researched previous threads and haven't found anything on this subject, if there is one can you please point me in that direction or any answers would be grateful.

You can turn off the VR(Voice Recognition) update in the settings. It's part of the iPod functionality. I turned mine off, with no ill effects. I just turn it back on when ever I load new music, and then back off again once it finishes.
