I would like to purchase a HD video camera? Does anyone know which is the most compatible with my iMac? I have a Mac OS X version 10.5.5. Do I have to buy special software to edit in HD. Do I have the capability to burn it in HD? 
The Canon HF100 is great for the price. It will work perfect with iMovie, FCE or FCP.
You cant burn HD footage on a DVD unless you only plan on playing it on a BlueRay player or mac. If you burn a standard DVD, the quality will be reduced.
Neither is the whole truth. HD video can be burnt to a standard DVD by making an AVCHD disc, which can then be read by compatible players (but not a regular DVD player). If you want to burn a DVD for folks to watch on their regular DVD players on their television sets, then you need to convert your HD movie to standard definition. DVD uses mpeg2 video, which is SD. AVCHD camcorders like the HF100 record a variant of mpeg4 using the H.264 codec.When you say you can't burn HD Footage to DVD do you mean the DVD will not be in HD but in SD or that it can't be done at all?

The reason why HD camcorders are a waste of money at this point. Unless youll be cropping and zooming, there is no final output acceptable of HD at this point in time.
The costs of HD vs SD camcorders can be staggering, and all you get is more pixels that you wont work with.
Do what you need, not what you want.
I'm very tempted by the prospect of HD but reading all that I am about HDV versus AVCHD, both needing to be converted to AIC...
HDV can only be edited natively in FCP. FCE and iMovie transcode into AIC.HDV can be edited natively in both iMovie and FC. My understanding is that it is not converted when transferred over the firewire cable, just like miniDV. AVCHD on the otherhand is converted.

Avid and Premiere Pro can edit HDV natively as well. I should've been more specific and said of Apple's first party software only FCP can edit HDV natively.What about Avid?
Hi,
I own a HDC-SD5 avchd camcorder and until August of this year I couldn't play my .m2ts files without transcoding them at least using AIC codec. Latest VLC (and mplayer and ffmpeg) makes use of new x264 libraries and it plays my avchd (.m2ts) videos perfectly on my 24 inches iMac mid 2007....
