I'm new to HTPC and before I try DVB-T I got myself a Anlogue TV tuner cheap to play with

When I record Analogue TVNZ, TV3, Prime etc what resolution should I capture at eg 768x576 etc

Note I playback is on a 29" CRT TV from a laptops TV out

I also assume that if I have specified a resolution higher than what is needed this is additional work for any Video Codecs ?

Analogue resolution should always be 720x576. You could also capture at 544x576 if you're capturing at a low bitrate which can decrease artifacts (but will however make the picture look 'soft').

Thank for the reply

My software defaulted to 768x576 I'll change to 720x576

In regards to bitrates I noticed that my Microsoft v2 MPEG4 codec defaults to 3000kbps yet the Divx v6.4 MPEG4 codec has 780kbps and the Xvid MPEG4 codec defaults to 878kbps

Which should I use especially since I have a low spec PC [P4 2.4Ghz] that tends to run at 80-100% CPU when recording in MPEG4

Not sure of the difference between Microsoft's MPEG4 and Divx/Xvid. Best to experiment and use the bitrate which suits your situation. I've encoded in Divx 768kbps before with pretty ok results.
