HD video

[Guest]

Asking for a friend at the best possible place I guess.

He is using a HD video camera when he is on vacation. Back home he wants to transfer, cut and convert this video material.

Which way should he save the movies on
a) HDD
b) DVD and/or Blu-Ray

to get the best quality possible.

It's not a matter of money in his case.

Help will be very much appreciated.
