OK, and reading the other truly informative thread, I have just done some further reading and the penny just dropped fr me in as much as this camera - SONY NX5 (apologies Leslie I meant the NX5, not just the X5 - correct?) - can simultaneously record to SD and HD on each of the 2 record devices - yes? In which case I would download and edit in SD and then swap out to the HD media? Would that be an option for me? Or would it be just better to transcode to something within Vegas?
Apologies if this is just a plain stupid observation/thought but I really would like to nail this HD upgrade path.
The NX5 appears to have all I want - except for saving that assurance of an on-the-shelf tape-backup option.
Grazie
