[jitter] Output quality with jit.qt.record

Hi. New to Jitter so sorry if this has a simple explanation, but I've been trying to output effected dv-pal .mov files with jit.qt.record and the results have been pretty substandard. What's the best option to use if I want no compression on the output file at all? I've tried various different codec options and they've all produced aliasing to a greater or lesser extent. 

Thanks,

Gavin
