What ROM are you using that isn't working with the camcorder? Even with the early CM9 ROMS and whatnot, the camcorder works.
Flash Harmonia 1.9 if you want the Froyo, Harmonia 2 if you want Gingerbread. If that doesn't work, you have a hardware fault.
You still aren't answering the question. What ROM are you using now? Have you flashed Harmonia 2 and tried the camcorder? Or are you testing on the same ROM and expecting a different result?
