8fps? That's quite bad. But first, try mencoder with lavc, it's the fastest 
around. Also, you could try capturing at 768x576 to obtain the best images 
out of tv card, and then rescale to some other value.

That's plain not true. Avidemux can do that happily, with frame precision.

Keeping full PAL is a strong task. My P4 2.4Ghz struggles with it, so I don't 
think it's possible for you. But you have to always keep in mind what your 
target is: I was like you before, when I realized I was going to burn VCDs 
only at 352x288, I started to capture at that res. Work like charm.
Also, on a final note, pay attention at the AVI dimensions: if you pass the 
2Gb file size, some programs could have problems, and if you pass 4Gb, you 
will definitely have problems with avidemux.
