Burning imported movies to DVD is dead easy in iLife. My little project to archive my DV tapes in DVD continues.
My MacBook had to work very hard in my first attempt which I selected 'best performance' in DVD quality. That took around 90 minutes. Yesterday I made another attempt using 'professional quality' which took more than 2 hours with CPU cranking to 80 deg C in temperature.
To be honest I couldn't tell much difference by my aged bare eyes.
