Post subject:  Change 6200 channel via firewire
Wanted to know the best way to have MythTV change channels on my Motorola 6200 via firewire. 6200ch no longer seems to be included and I can't seem to find it anywhere on the net. Myth seems to have a new method for changing channels via firewire but how do I get it to do it without also capturing from the Firewire port (which i was also unable to get to work)?

I am capturing from the S-video port on a pvr350 and want to know what to put in the External channel changing field in the setup. Looked at an irblaster but I have no serial port on my shuttle box.

TIA

I downloaded myth .18 and extracted 6200ch.c from there. I compiled it and now when i run it i get the following:

root@mythtv:~/mythtv-0.18/contrib# ./6200ch 10
Could not find Motorola DCT-6200 on the 1394 bus.


To add some more info:

This is the output of plugreport:

here is more detail with 6200ch:

root@mythtv:~/mythtv-0.18/contrib# ./6200ch -v 10
node 1: vendor_id = 0x0000301b model_id = 0x00000000
Could not find Motorola DCT-6200 on the 1394 bus.


I added my vendor and model ids to the 6200ch.c recompiled and i now get:
root@mythtv:~/mythtv-0.18/contrib# ./6200ch -v 10
node 1: vendor_id = 0x0000301b model_id = 0x00000000
Warning: Unit Spec ID different.
Warning: Unit Software Version different.
AV/C Command: 010 = Op1=0x00487C20 Op2=0x00487C21 Op3=0x00487C20

And nothing happens on the box.
