Nope everything built in.
Install software.
Put DVD in drive
Click which bits you want i.e. main movie only, no trailers, which language etc.
Rip movie (Takes about as long as the movie plays for).
Out pops MP4 file suitable for loading into Ipod, PSP, whatever.
It also copies and clones DVD's.
It's one of them bits of software that just works.
Get the Platimum (mobile) version.
Just checked and I see the price has gone up.
You need the basic version first (57 Euros), then get the mobile option (34.60Euros) so I guess the best part of £80.
Not cheap but, like I say, it works.
I think when I got it a couple of years ago it was about £50
