I think I see some of what you are saying here... when you say 'converting', I'll assume you mean 'ripping', as without the mobile option, there is really nothing being converted.
With regards to the time it is taking, there is no reason I can think of, except either a dirty or scratched source disk, or a bad pressing (poorly made) which may or may not show up on playback on your set-top.
Take any of your source disks (non-region 2), give it a good cleaning and inspection, and try again...if it's still a problem, take it back to where you bought it & see if they'll exchange it for you.
P.S. Make sure pathplayer is enabled...
P.P.S. Is DMA enabled on your system?
