Let me try...
On the Sony site I found a DCR-SR60 and not a DCR-SR60E, but probably this is not an issue.
Then, I don't think iLife 08 and Intel processors are a requirement.
Based on other posts and specifically on my own experience in using MPEG Streamclip I suggest you to:
o- connect using USB: I don't think USB 1 vs. 2 should make a difference other then for speed; but this I really don't know;
o- copy the MPEG2 files from the camera to the finder;
o- open MPEG Streamclip (free), but if you don't have FCP you must first buy the 20$ Quicktime MPEG2 component from Apple;
o- from MPEG Streamclip Open the file(s) you copied from the camera;
o- then, if you want to edit with iMovie (
any version) *Export to DV*, and make sure you choose the correct codecs (DV-PAL vs. DV-NTSC)
o- if instead you want to use FCP/FCE,
Export to QuickTime (cmd-E - NOT Export to DV!) with Compression: Apple DV-PAL (or Apple DV-DVCPRO/NTSC), Quality: 100%, fps: 25 for PAL or 29,97 for NTSC, Audio: uncompressed, Stereo, 48 KHz.
In either case you'll get a movie file that can be easily imported to the editing application.
