service could not be found

    I have Dreambox 600 and I got "service could not be found" message on some channels


    I search most of dreambox sites and I could not find a good answer




    What I did is




    1- replace the box by new one (same problem)


    2- replace LNP's and switch and did automatic search and it worked for one day and then I got the message again for some channels


    3- at the end I noticed that if I have missing channel and goto the manual TP search I found that the TP frequency is not correct so I correct it manually then research so I got the channel with clear picture




    note there is no change on /etc/satellites.xml




    Can any one help me to fix this problem or from Linux point of view how can I keep the TP frequency as I entered it ?




    Thank you in advance
