Corrupting Channel List

Hi,

I have a dreambox 600s and when staying on a channel for about 1 hour or more, when I change that channel and get back to it again, the message 'The service could not be found' appears. The SNR changes from 98% to 86% to 76% to 98% etc... The BER will go up to thousands as well. To fix the problem I have to upload the channel list again and reboot. Even If I upload the same channel list will work. I tried another different channel list from another provider. Problem remained. Do you think that it will work if I re-flash the image to the box? Any help before reflashing will be appreciated. Thanks!

Re:

Thanks all of you. I re-flashed, then I'll see how it goes and I will inform you.

I have another problem now since I re-flashed.. All satellites are working (with the motor) but when I try a channel on 28.2 East the motor doesn't turn. It says service could not be found and stays there. It doesn't even try to turn, and only on this satellite.

Thanks!

Re:

Thanks all of you. Probably I had an error in the satellites.xml or services because when I uploaded them again it worked perfectly. Thanks again!

Channel list corrupted again :/

I reflashed it 2 days ago and still corrupting. Probably I'll try another image as I'm using Darkstar II at the moment.
