Thanks Steve, for this and the rest of your help!

I'm trying to figure out the issue with this firewire thing. My laptop is
perfectly accurate when changing channels but my mythbox isn't. theres a
couple differences between the two though. Since this comes up so much as a
problem for people I want to start collecting information on the issue to see
if I can find out where the problem is.
Could anyone that is using firewire to control a Motorola DCT-6xxx series
cable box respond to me off list with the following info:
1. firewire chipset being used (lspci|grep FireWire)
[EMAIL PROTECTED] proc]# lspci|grep FireWire
00:0b.0 FireWire (IEEE 1394): VIA Technologies, Inc. IEEE 1394 Host
Controller (rev 80)
2. your plugreport output for the Node connected to the DCT.
[EMAIL PROTECTED] proc]# plugreport
Host Adapter 0
==============
Node 0 GUID 0x00152ffffed1547e
------------------------------
oMPR n_plugs=1, data_rate=2, bcast_channel=63
oPCR[0] online=1, bcast_connection=0, n_p2p_connections=0
channel=0, data_rate=2, overhead_id=0, payload=376
iMPR n_plugs=0, data_rate=2
Node 1 GUID 0x0011d800003491ed
------------------------------
libiec61883 error: error reading oMPR
libiec61883 error: error reading iMPR
3. the output from a 6200ch -v channel change
[EMAIL PROTECTED] contrib]# ./6200ch -v 120
node 0: vendor_id = 0x0000152f model_id = 0x000064cb
AV/C Command: 120 = Op1=0x00487C21 Op2=0x00487C22 Op3=0x00487C20
(I had to change some vendor and model ID numbers in the 6200ch source)
4. Your Kernel (uname -r)
[EMAIL PROTECTED] contrib]# uname -r
2.6.14-1.1644_F
5. Your 'modinfo raw1394' output
[EMAIL PROTECTED] proc]# modinfo raw1394

6. your accuracy rate (0 - 5, 5=perfect channel changes, 0=numbers get
detected but rarely does it work).
5 - The channel change always works, I think. Since so many recordings
are messed up, it's possible the channel changes are not working
perfectly and I don't notice.
7. a brief description of what your box does when you try and change channels.
I have a brief description of what happens to me below in the quoted email.
This is with a DCT-6412.
The channel change always works, but video input only works sporadically
(25-33% of the time). I can reproduce this with test-mpeg2, so it's not
a mythtv thing. Steve Adeff has given me some good help, and I'm
looking at swapping my DCT-6412 for a normal DCT-6200. The more I play
with this box, the more truly broken is seems.

Hopefully we can figure this out and end the problem.
