You can use a firewire connection to get video from the cablebox?? So in essence you dont need a capture card?? just FW and an ir blaster to change the channel??

Hey everyone,

I was wondering if anyone had this box working under linux + mythTV 
0.22.  I've been at it for a few hours and haven't been able to even 
pass the firewire_tester.  I've called up my cable company and they said 
that they enable all ports on their boxes.

I'm running Fedora 12:   Kernel: 2.6.31.5-127.fc12.x86_64

libraw1394-2.0.4-1.fc12.x86_64

Everything fails :(

I've tried both firewire ports on the back of the STB.  I've also tried 
turning the STB off for ~30 seconds, letting it boot and plugging it 
back in.

Anyone have any ideas?  Part of me thinks the ports are really disabled, 
even though the Cablevision Rep told me they were all on.

Thanks

Christopher
