I just feel I want to add one last thing here withou getting into an HDV vs SD argument.

I hav a four year old P4 3Ghz PC with 2GB of cheapish RAM. I like the extra pixels (if that's how we want to refer to it) that I get from my HDV camera. I always edit HDV and can get a 25mbps result from it when mastering to blu-ray. The image quality is much superior to any SD disks I've ever produced. For me the resutls speak for themselves. I'm not pretending I get the same image quality as I see when I watch Casino Royale in blu-ray but then my productions cost five-bob tomake and not 100 million....

What's more, I spent a few quid on a plugin for Premiere Pro and even on this old system I can edit, scrub and add a few effects and work in REAL-TIME.

I do not edit M2T files but have an intermediate codec which allows me to edit an uncompressed AVI file. Disk space (45Gb per hour of footage) is my only bug-bear.

Never had an issue with chroma key (done in After Effect v7 using Keylight plugin).

Horses for courses. I like HDV and will stick with it until I can afford soemthing better that record full HD.
