It's not a problem with Firewire, it's a problem with the implementation in
the cable box. The reason it sucks is because nobody has an incentive to
make it better.
Your USB peripherals work reliably because their manufacturers have a
financial stake in their functionality - if they didn't work, they wouldn't
be able to sell them.
Firewire outputs on cable boxes, on the other hand, wouldn't even be there
if the cable company had it's way. They are only there because the FCC
mandated they be there. The FCC probably doesn't even really care at this
point. When the mandate was handed down they thought that Firewire
interfaces would become common on TVs. They didn't, but the mandate
Now we have a situation where there are 60 million or so cable boxes in use
and maybe 10,000 people who care about being able to use Firewire output -
and to make matters worse, those Firewire users are just trying to avoid
paying for a cable company DVR.
If the Firewire reliability sucks enough, you will just get a cable company
DVR, which makes both Motorola and the Cable Company happy.
In short, Firewire output doesn't work because nobody in charge of the
implementation cares to make it work.
