Hi,
I´m experiencing the same prolem on my Unicable-System:
Box: DM800S - directly connected to LNB
Image: iCVS-Image-dm800-20090121173454
LNB: Kathrein UAS481
Dish: 90cm
Satellite: Astra 1F/1G/1H/1KR/1L/1M @ 19.2E
I have two symptoms for this:
1) There are a lot of transponders, where the DM wont find any chanels at all. (Eg. transponder 107 on 12,5450 broadcasting 6 german FTA chanels).
Running the satfinder tuned on the settings of transponder 107 (Freq. 12,5450 GHz, Pol. H, SR 22000, FEC 5/6) returnes good values: SNR 17.0 db and an errorate of 0.
Any kind of channel scan doesn't return a match on this transponder.
I have tried to add one of the services manually using the "DreamBoxEdit" tool, but the tuning in still fails. Interestingly in the info bar the SNR and EBR is reported with the same value as seen in the satfinder.
Changing the tone_amplitude to any value between 5 and 11 didn't help either.
("echo # > /proc/stb/frontend/0/tone_amplitude" via telnet, where # stands for the value to be set)
2) Zapping between the channels found via manual scan (FTA only) often results in the "Tuning failed (SID not found in PAT)" error. "Often" means, that these chanels sometimes are found and displayed correctly.
Before writing this post I spent a lot of time searching this board for people with similiar problems and perhaps a useful solution, but none worked for me.
In some threads of this board a lot of DiSEqC settings are mentioned for various DiSEqC-switches without any comment.
I don't think it is worth trying to use theese settings on a unicable LNB without knowing what they do and how they will affet the LNB function.
I know, the image i used is not an original DMM, but i need it for unicable. And the uploader Schaedelmeister used the most recent CVS as base for it.
My questions now are:
What is the "PAT" and can I edit it? (If yes, is it worth trying, and how?)
How does the tone_amplitude affect the operation of DiSEqC?
Where can I find enough informations about DiSEqC commands for unicable systems to understand the settings in the satelliteequipmentcontrol-plugin?

EDIT (2009 01 28):
As unicable now is supported in the experimental DMM images i switched back to the original.
Now running ist "experimental-dm800_20090126".
A good sideeffect is, that my iDream Remote (iPhone App) is working now. - But the "SID not found in PAT" behaviour is still the same.
