Just finished setting up and though it would be helpful for someone else
So lets see... starting from the beginning...
I'm capturing from a satellite receiver (PAL) via composite video and 2 RCA cables for sound, connected to the soundcard's linein (a C-media onboard card, which I had to patch a nasty bug, info here
Next, I installed the btwincap driver for my tv tuner card, and ffdshow for deinterlacing and resize filters.
After some testing and web research, I've settled with capturing at 768x576 (YUY2) through ffdshow, deinterlacing the signal with TomsMoComp (swap fields on, 5, vertical filter), the swap fields is needed for PAL from what I've read... Then the resize to 384x288 (half) via Simple Resize (acceptable quality and fast), and finally the encoding:
Video - x264vfw, 322kbps ABR, Subme 6, Me hex (can't use the umh for cpu reasons...), threads 3 (P4 3.2GHz HT Prescott)
Audio - LAME MP3 48kbps ABR (32kbps min, 64kbps max), before you say anything
I've tried AAC+ from the shoutcast dsp plugin, but I got skipping audio (?!), and somehow MP3 sounds pretty acceptable with this settings.
That gives me a stream with 370kbps ABR combined, which looks and sounds "awesome"
Maybe this helps someone trying to setup NSV...
And as a last word, NSV is a really great format, and the shoutcast server is very portable and low on resources usage... save for the bandwidth usage
Sorry for any typos, but english isn't my primary language.
