So, given the dual CPU available to me right now, should I proceed with the purchase of a capture card, or am I waving the proverbial in the wind?

If you use hardware encoding capture cards (DVB-T does this, and analogue capture cards like the PVR-250) you don't need a lot of CPU for the capture of the video.
I believe the DVB cards actually don't do any encoding but neither do they do any decoding, they just stream the compressed video feed they pull of the air in whatever codec they receive it in (usually MPEG2), but the result is the same, both the hardware encoders (Hauppauge PVR cards) and the assorted digital TV cards place little demands on the backend CPU.
Not sure if the CPUs will be enough for playback though. But I've played back my recordings on a P3-700 with no problems (from a remote backend).
If the G4 is to be used as a frontend as well and CPU is a problem then you could output through a PVR 350 card (as long as your not planing to trascode stuff to MPEG4 for storage) or an nvidia card using XvMC (particularly as some of the new GPUs allegedly have MPEG4 assistance) as both would assist with the decoding, but, I have *no* idea if either would work in a PPC environment.
I wouldn't expect it to be easy though as *all* the documents are written from an i386 perspective
