mixing 30p and 24p
 

I am shooting a doc using JVC hd100ua camera in HDV 24p mode and also some fotage on a canon optura 60 30p mode. Both widescreen. So how do I convert the sd 30p footage to hdv24p?
Could I hook canon sd camera up and play while recording to the JVCHD100 camera?
Or is there a way in vegas to do this. Final output is DVD.
