I have to confess,I seldom "tamper" with those settings
I have tried the different interlacing options and found using the lower field first ( bottom) to give me the most consistent results
This is within Avid liquid, Sony Vegas and Canopus Procoder2 . It is also the default setting. Also the encoding software are not equal in ability and MainConcept ( which ships with a few video editors as plug-ins) make better standalone encoders
As for deinterlace method. I actually do nothing or use weave. On occasion Ive simply gone ahead and output as progressive with varying results but this is OK on the PC not on a DVD
I seldom resize too but from experience with Photoshop.. I Use bicubic mainly out of familiarity as Im used to what to expect from it. All the methods use various extrapolation algorithms and i think their output is simple more similar than not
I dont believe there is one "best" method and it is really very dependent on the source of the footage and how it was originally captured.. a fact many camcorder manufacturers do not always disclose so it boils down to many of us to
trial and Error
