I have firewire or iLink and a sony HC42E handycam. My software is IUVCR, Windows Movie Maker and Windows Media Encodee

The IUVCR works very well, except in fullscreen preview mode I experience the following:
1> Audio/Video becomes out of sync after a while.
2> The image in fast motion situations looks interlaced
3> My captured vid is 1.66:1 or whatever (widescreen), and it displays squashed TV ratio.
Are there ways around these issues?

Concerning capturing, I have tried WMM and WME(encoder). Too high quality makes WME not work (audio) and also the CPU load is too high for any decent capturing... have a 2.6+ AthlonXP with 1GB RAM (and now firewire)? In addition, it seems (again) interlaced and non-widescreen format.

Any help will be appreciated.
