hi, I have a problem of drop frames. I work SD , capture my video dv-pal into 1T portable hard-disk with 800 FW port. I have MacPro 2 x 2.8 gHz quad-core and 2G memory . My Sequence settings are good, I have 1 video track and 2 sound tracks, my music has AIFF codec. My problem is that I can't work on my time line in real time. I need to put compression data rate on quoter, and work in safe RT mode. I work only with 1 sequence open. and my real-time audio tracks on 8 I think there is another problem that cause this drop frame problem. Please help me to start checking every step during my editing work. Thank you very much for your help, Ran.
