Hi Clive,
Personally I produce to whatever mpg suits you best from mp4 then convert to flv using pazera for upload to SMWOV.
If you join/have joined SMWOV the extras pages have the link to Pazera and some suggested profiles to try.
I believe the SMWOV system does convert but if you can do it yourself it gives you greater control.
Cheers
Adrian
