I’m using a 1.5GHz Powerbook with 1Gb of RAM.
Your post got my gears rolling. I think my problem is that I’m capturing to a drive that’s connected to the laptop via USB 2.0. I’ve edited that way, but never captured before. I’m going to try again tomorrow through the firewire port and see if there’s an improvement.
Also, I alreay trashed the prefs and repaired disk permissions. No luck.
Not really sure where to find out about buffer size or speed.
