Thank you Steve for trying to find a common thread in all of this.

>3. the output from a 6200ch -v channel change
The id for this box was not included in the 6200ch program so I had to 
manually add it to get the channel changes to work.  However, the 
program runs perfectly and it able to change the channel flawlessly 100% 
of the time.

./6200ch -v -n 1 3
starting with node: 1
node 1: vendor_id = 0x000014e8 model_id = 0x0000620a

>6. your accuracy rate (0 - 5, 5=perfect channel changes, 0=numbers get

5 - channel changes always occur flawlessly, as far as I can tell..

>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.
Channel changing always works, but I only seem to be able to receive a 
stream from the cable box about 30% of the time.  I have yet to figure 
out what the circumstances are that yield valid captures, because 
successful recordings seem to occur at random.
