Hi everyone,

I have a MythTV network at my house that I have been using mainly for
sharing movies hosted on the backend to remote frontends.

I have two DirecTV receivers hooked up to my backend via two PVR-150's. The
model #'s are D12-100 & D12-700.

I can change channels on the D12-100 receiver via directv.pl on the command
line (haven't tried in MythTV), but the D12-700 times out no matter what
command is sent. I have both of them hooked up via identical pl2303 chipset
serial 2 usb adapters with a null modem adapter in between. Again, the hook
up is identical and the D12-100 works with no issues.

Here is an output from the CLI with the D12-700 with the directv3.pl script
floating around:

alan at server:~$ ./directv3.pl port /dev/D12-700 box_type D11 verbose

Anyone got any ideas? I have not even found anyone posting anything about a
D12-700 box with MythTV yet.
