Which version should i use for Vegas?
Aspect HD
Prospect HD
NEO HDV
Or what are others using. I think this will help me.

Cheers
Simon

- Vegas & Final Cut Pro work with the NEO line: NEO HDV, NEO HD, and NEO 4K
- Premiere Pro on Windows works with Aspect HD and Prospect HD/4K.
- Most applications in Windows or Mac OS X use the NEO line: NEO HDV, NEO HD, and NEO 4K

Re: Cineform website
I love Cineform and their support is excellent, but I agree about their website. It's like a firehose of information. It's almost easier to google the site than use it.
