Ok here is the run down.

I had a gentoo install of mythtv i compiled dct-channel and was able to change the channel on my digital cable box through serial. It had a binch of issues and i wanted a fresh start so I reloaded with knoppmyth since it would be much faster.

I unpacked mythtv src and compiled dct-channel
now i cant change the channel anymore.



but if i do something like


my digital cable box will act funny. for example it will switch on the display from the current channel to 0 then back to current channel then to 0 ect .... several times then it just suts off.

So it appears that i am getting something sent through or my box wouldnt freak out and power down when i force it. regular channel change dosnt work



and yes 400 is a valid channel for me. ive also tried with other channels but now im totally baffeled and lost as to why it was working and now isnt workiing.
