Thanks so much for the explanation. And to answer your question, yes this
is really just a learning experience for me (since I love the challenge of
figuring out how to make something work) but I understand it's sometimes a
waste of time. I know I can purchase a CableCard from Comcast (I already
called and spoke to someone about how to obtain on) but I was just looking
at what options are available with my STB using Firewire.
So far the STB seems to be able to do everything I ask it via firewire fine
(which seemed really encouraging), and MythTV sees the device okay (it id's
it as SA-8KG5-CRONUS-LinuxJUL23200) which I assumed was a Scientific
Atlanta since that's also the type of cable card it has, but someone else
told me it was actually Cisco. Anyhow, my next step is really just to see
if I can get it to show me Live TV, so far it's not working.
Any ideas on where I might look?
