I just had a scan at SKG in Subi (SJOG) and she did a 3D without me even asking, it is just another US head...
I would get the referral rewritten for somewhere else and try that.
Also, not sure about DVDs at all - never had one offered to me at all, only the films and the CDs (which you can play on a computer or any other DVD player that will play burnt discs.

HTH

Also, are you going to go through the midwife clinic at KEMH?
