Just purchased one of these and installed the FlipShare software. I am getting very choppy playback on my computer using the software/iTunes/Quicktime. Flip support has told me that my iMac processor (2.1 Ghz PowerPC G5) is not adequate for streaming playback of the videos (.MP4) and that I need an Intel Core Duo chip. Is there any way around buying a new computer to get quality playback of my videos? Thanks in advance, a bit of a Lehman when it comes to these things.
