i have a Torch and a Macbook Pro..
i have 45 GB of music and video collection.
i never had any problems with tags or those question marks (?) that you've mentioned.
and i didn't have any problems with songs/videos being misplaced on a different file.
most of the members here believe it's a USER error.
C'mon guys.. blame the PS3, blame the Torch, blame the laptop but not the USER.
it's the machine's fault that they didn't explain/communicate themselves clearly to the USER.
hehehe....seems like you may have a point!
For sjorge3442....you have a very good point.
I use iTunes for everything, but on the BB Torch, I add music through the BB Desktop manager and I do not have that problem of '?' or whatever!
