doesnt the HG10 work on the good old HDD format, Which means he has quite rightly just coppyed the rushes over onto his own hard drive with the USB. I know from working with other HDD footage thats been dumped on me that Adobe PPro dosn't handle the footage very well....or at all tbh! Where as Vegas worked perfectly for it! I have persnally always found NFTS a bit better for video editing persnally, so you could maybe start a new partition and try that. Just to confirm-You have put the rushes on your computer?
