Nokia 9800 modification for svhs??

[jascha]

Hi,
I would like to be able to make a modification in my 9800 to be able to output a svhs signal or even better to component video. I need to output to an analogue to digital converter for my pc (firewire) to be able to capture in avi format for editing on my pc. As at the moment the only way i can work is by using an output from my scart lead out to a composite video out, the quality is degraded and detail in picture lost considerably and hence i would like to be able to output from my 9800 in higher resolution. (720 lines would be even better if there was a way!!!!).
The connector in my converter is svhs and would like to input in svhs or better to capture better detail.

Hope someone has a clever way of doing this modification if you had a circuit diagram (which i don't!!!!). I can modify though.
Any other ideas very welcome
Thanks
