I need to order a HD cam corder for work. I work in IT at a dental hospital and we want to film some clinical procedures that take place and then edit these and stick them on dvd. I have looked around a bit but know very little on the subject. I have seen this one which seem pretty good http://www.ciao.co.uk/Sony_Handycam_HDR_SR12E__6870712 Some people have mentioned the sony camera don't work well with macs can anyone back this up. also I use final cut 4 on my mac book(2.2ghz with 2gig of ram) for editing the video, will I notice a huge differance with a mac book pro with 4gig of ram?
