Hello I have a Sony DCR-TRV255E Camcorder and I would like to transfer tapes to my MacBook in order to edit the files with iMovie. The Camcorder has no firewire connection, only USB. There are no official drivers for this camcorder for mac os on the Sony website and my MacBook does not recognise the camcorder (USB stream is switched on). Does anyone know a way around? Thanks a lot in advance!!
