Anyone know where the cheapest place to buy Mini DV tapes for my sony trv19? I bought some from argos cost me £10 for 2 TDK tapes. i'm a bit confused though as my trv 19 manual keeps going on about tapes with cassette memory but i haven't seen such a thing. Also i want to be able to edit tapes etc on pc (via firwire) and then for now convert to vcd any ideas what programs i would need for doing this? (cheapest possible my budget has been taken up buying the camcorder).
