The BF requires "compliant devices" not to transmit unencrypted
high-def streams over any user-accessible bus. Instead, they must
implement the flag in a manner "robust against user modification" --
so if they'd seen the flag, they could only allow down-rez'd signals
over the PCI bus for capture or playback.
That's why it would be impossible to build a MythTV system around a
BF-compliant card. Anytime the flag were applied, you wouldn't be
able to get the stream at all.
