I'm using a JVC GR-D70 to capture my miniDV footage that was shot using a DVX100 on to my NLE(FCP). My question is, i'm I losing quality or res when using the JVC as a playback/capture device?

Not if you're using firewire you won't be.

All MiniDV is the same resolution, 720x480. The cameras are just writing data then reading data, just like if it was on a hard drive, CD, or DVD media. The MiniDV tape is just a large, reusable storage device.

Thanks for the info fellas....
