I've been considering getting a nebula TV card for PVR duties. Ordinarily I'd just bung a PCI version in my HTPC but I'm wondering if it would be more useful to have a USB version and share it amongst my 3 PCs (HTPC , serious use desktop and little laptop) Any disadvantages with the USB version ( I don't need composite capture)? Also how much oomph do you need to use the nebula? Ideally I'd like to be able to record on my HTPC and still be able to watch Theatertek or Dscaler or use winamp. I've got a 1.13 P3 (could buy a 1.4 though) with 512m and a radeon VE , Have I got enough poke to record in the background ( doubt it with Dscaler to be honest). What are peoples experiences? Any other suggestions? The PVR250 I hear mentioned a fair bit and it features hardware encoding I believe..
