Well, I'll try to notify PowerTV. However, you can probably see where
this might lead: PowerTV will say that they didn't write the toolkit,
they just license it from Red Hat, which in turn will say they can't
support you, you'll need a service contract.

Anyway, I'll get the balling rolling at work so we can start contacting
PowerTV and Red Hat.

Actually, I think two other folks have reported issues that might be
related to this. However, IIRC they were told that this list doesn't
provide free support for the GNUPro 99 tools, and that they had to
purchase a support contract, which is entirely reasonable IMO.
