1) What format is the video when it is on the hard drive or DVD? Specifically, what compression is being used?

2) All appear to be standard def - where is the high-def version?

3) There is no visible accessory shoe... external mics and/or lights need an adapter (like the Canon Elura 100)? Though the spec sheet has an "x" for an accessory adapter... and hot-shoe. If that's the case, what accessories are there?

4) "xlr in" on all models? Really? Call me a skeptic, but I find that pretty amazing... or am I reading the spec sheets wrong?

5) Touchscreen... how "Sony-ish" of them...
