i just bought a DVX100b for dirt cheap with only 44 hours, the reason i got it for so cheap was that the mic had been broken off but i use to film skateboarding so wasnt to concerned with it since it came with external mic that works just fine. now hear is my issue, i have now purchased a LED light but with only 1 shoe mount i cant use both(the external mic is rectangular at mount point so the holder doesnt work) so i bought 2 DVX100a for parts off ebay without thinking about whether or not they were interchangable, and they dont appear to be... so my question is, can it be swapped? FYI this is my first camera ive ever purchased so i dont know hardly anything about cameras at all. but i am mechanically inclined and had no issues removing the mic from the dvx100a but since the ports for the ribbons are visable on my dvx100b i can see that they are not the same. did i just waste my money buying to broken cameras? are there any other parts that are interchangable?
