The DVX and HVX have real similar looks (I’ve used both) because they use the same CineGamma technology, and have similar custom options.
If you have to shoot HD now, then you’re best off with the HVX. If you’re on more of a budget (P2 cards are still pricey, but CitiDISK and Firestore have you covered) then the DVX is still a great option. The documentary Murderball was shot using the DVX100a, and it’s up for an Acadamy Award this year!
Go with what your budget dictates, and if your story is there, it won’t matter if you’re shooting on Pixelvision or DVC-HD format.
