Hmm. A 'pipe' tuner as described above might be a useful accessory function for
mythtv. As well as following the Unix philosophy, it would permit users to
handle those odd, obscure sources people occasionally mention on here by
allowing handing-off to an external video collector program.
Currently the only way I can see this requirement being handled is by using the
loopback address and one of the stream plugins like mythnetvision.
