Maybe call the u/s place and ask, that's what I did.

I wrote a list of questions like about payment method options and getting a dvd done, reception was able to tell me what technology was in the room my appt's in (think one of the rooms only does VHS videos) and that I could bring in a dvd or pay $10 for one of theirs.
She wasn't sure what sort of dvd I needed so I think I'll just buy it

But yeah, call and ask, where you have your u/s should be able to give you the info you need.

All the best!
