I am designing a new system, which I would like to have the capacity to convert VHS for digital storage. My current system takes DV via standard 1394 port using a "soft Codec" - I have never had a hardware video capture card. So now I am thinking - why not continue using "soft capture", plus get an All-In-One Video Card to do the VHS A/D conversion. What are the benefits and disadvantages of this or have I misunderstood A/D converting?
