Almost the same here, but I have a couple of issues with the c1 und c2 modes:
1. I can't register a custom wb while in c1/c2. Why??
2. AutoISO: While in c2 with ISO set to auto I get a reading of the used ISO when half-pressing the shutter button before recording. With the same settings but in c1/movie mode the display always shows "AUTO ISO" even when half-pression the shutter. I don't need a continous display of the ISO value, but a staring value before you actually shot is very helpful.
