The videohelp site is a good place for leads on programs,
and also gives ideas on program cost. GetFLV is expensive,
because it's a rolling hack, and needs to be updated
on a regular basis by whoever wrote it. There are only three
reviews here, but I've learned all I need to know. It
looks like you're provided a fake (or otherwise) auth code,
to download CBS.
