This issue is one of the reasons I went with HDV on MiniDV tape.
Thank God, I looked here before I bought my new Camcorder, I was about to pick up one of the HDD units. Seeing that it did not have a Firewire connector I began to look into that issue.
I even posted a thread here titled " What Does It Take To Get Firewire "
All responses led me to HDV.
To The OP:
Can you not return it on the basis that it is not compatible with your computer?
Not sure about making returns in the UK as I am in the US an I know consumer laws vary widely.
My guess would be yes.
Can someone answer this, will an HD camcorder play back a mini-DV tape recorded on a non-HD camcorder? You know, like when it's time to upgrade because the old Mini-DV Cam dies...
I have about a hundred tapes in DV ( MiniDV ) format recorded on a Sony DCR-TRV-11.
They all playback on my new Canon HDV ( MiniDV ) camcorder.
So yes they are backwards compatible, for now.
On the Canon HV30 I can even RECORD in DV format if I desired to do so.
ALSO I have recorded HDV on normal old MiniDV tapes instead of the HD MiniDV tapes.
