If you just want to watch the recordings, not to save them, just connect the 630 HDMI to your monitor if it has an HDMI or to DVI (you need an HDMI to DVI adapter cable). You wil also need to get the sound out and connected to external speakers in some way (can even go to the input of your PC sound card for example). You need a monitor which supports HDPC (almost all newer ones do). Of course this is watching on your monitor not on your PC but if you don't want to keep the recording is the same. If you don't care about HD only SD you can use any video card with video input or an USB video graber (there are many), and connect the composite signal from the PVR to the graber input.
