I'm in the market for an analog to digital converter. Right now, I'm using an old Canon ZR60 to bring in my analog sources, but it's on the verge of dying and I'm looking at buying a dedicated converter. I wondered if anyone had some suggestions as to what converter to use. I'd prefer a PCI card, but a firewire box is OK too. I should note that I need a bidirectional converter--I need to be able to bring video in through it, and send video out to a TV (I use an NTSC monitor while editing.) Any suggestions? Thanks in advance!
