I am using a Canon XA 10HD that uses .MTS files. I know I have audio because it plays back fine, yet when I put into onto my Terra Drive and try to edit the audio either won't play or lags real bad. I'm not sure if I have a settings problems or if my drives throughput is to slow? Any help would be appreciated.
Ask in the Premiere forum and provide proper technical info about your system, your project settings etc. You have not doen that, so nobody can even begin to guess.
