Please ,
Make it easy to understand: DL could mean Dual Layer.. in your case you mean download
Your in ability to capture ( that is the correct term) footage on your tapes to the PC has nothing to do with Nero
Footage on MiniDV tapes are recorded in a digital format which only needs a
firewire option for PC capture
HDD/SD card camcorders ( also digital ) use
USB for transfer to PC
However, Hi 8 tapes are
analogue as such in order to get then on a PC you need to have hardware that will digitise them first, or on the fly
There are several ways which involve more than just using a bog standard PC
TV cards ( with video input) , little gizmo ( Google "
Dazzle") or costliwe
ADVC it
compatible Digital 8 camcorders ect ( they play Hi 8 but have firewire to enable PC capture ) Sadly not all do it and Sony doesnt make then any more but ebay might have some just make sure they are compatible)
You can also simply get a setop DVD recorder and use that to make DVDs .. Footage from the DVD videos can then simply be copied to PC if editing is desirable
