I recently directed a concert with seven Xl's and four Panny dvx's. In post, I have had trouble with the fact that Xl's are drop frame, and Panny 24p's are non-drop. Avid won't allow multicamera grouping with non-drop and drop footage.

Any way to change the cameras to record either?

I know that I can dubb the minority format to new tapes, but, barring that, any suggestions?

what are you capturing with? Can you reconfigure your capture setting to see your deck differently?

I'm cutting on Avid Xpress pro using a JVC sr-vs30 deck. I will look into changing the settings, but the editor who loaded the footage has been cutting on Avid for four or five years. I assume he would have altered the settings, if he could, to make the footage uniform. It may be a 24p thing, with the pulldown and whatnot. hmmm
