WMV whether Standard or advanced is a very bad choice then.
[Matt Jones] “720×540 windows media file straight out of After effects using the export wmv command and flip4Mac. I’m using a 2-pass CBR of 400 @ 15 fps.”
720×540 at 400Kb/s is very aggressive – is the content mostly static? You should be able to double that bit rate easily.
Why 15fps? – even a crappy old mobile device can handle a full frame rate.
If you want the widest compatibility use MPEG-4 SP or MPEG-1, not WMV.

Just because it’s an ‘old’ regular TV does not mean the source needs to be interlaced.
Interlace was used to get over ‘bandwidth’ restrictions.

You need to. Use the Frame Controls in Compressor to perform this.

720p or 1080i?

What version of compressor are you using?
Have you opened it in Quicktime, if so what information does that give you?

Compressor is certainly up to the job. Are you trying to make an AC3 surround file out of a stereo source?. Obviously AC3 can be just 2 channels but you need to specify this in the Audio tab settings.
All this is very clearly run through in the Compressor manual.

‘None’ in this case means no compression, despite ‘CODEC’ meaning COmpression DEcompression, a ‘None CODEC’ is an uncompressed CODEC. Remember both AVI and Quicktime are just wrappers for CODECs.

You can export Uncompressed AVI out of Quicktime Pro 7 on a Mac.

If they need i-frame only or uncompressed it’s for a reason and as such given them a LongGOP file (the other formats you list are all LongGOP except JPEG2000) is likely to be unacceptable.
It might be worth contacting Click Effects to see what they do support?
