[mythtv-users] Channel changer for Motorola DCT3412

[Harry Devine]

I have a Motorola DCT3412 STB from Comcast, and I can't seem to find a 
channel changer for Firewire that'll work for it.  I'm trying to get 
Firewire working from my Myth box to see (hopefully) if I can get access 
to all of the channels that my pcHDTV can't tune (see my other topic 
here: http://www.gossamer-threads.com/lists/mythtv/users/295792). 

I compiled the 6200ch program in the channel_changers directory, and 
when I run it, it says "Could not fine Motorola DCT-6200 on the 1394 
bus".  I know that my firewire connection is working, because when I run 
plugreport, it returns the following:

Node 0 GUID 0x00159afffe163f4a
------------------------------------
oMPR n_plugs=1, data_rate=2, bcast_channel=63
oPCR[0] online=1, bcast_connection=0, n_p2p_connections=0
               channel=63, data_rate=1, overhead_id=0, payload=376
iMPR n_plugs=0, data_rate=2

If I run 6200ch as follows (6200ch -v -n0 68), I get the following for 
the vendor_id:
         vendor_id = 0x0000159a model_id = 0x000034cb

Does a channel changer exist for this STB, or can the existing 6200ch.c 
file be tweaked to work?  Also, my STB has 2 tuners in it, so when I am 
watching a program and one is due to record, it'll switch to the 2nd 
tuner and record off of that while I watch something on the other one.  
Will these channel changer programs mimic the same functionality?

Thanks for any help,
Harry
