Hi,
I’m using vdr 1.3.12 with a single DVB-c premium (ves1820 frontend) on a kernel 2.4.26.
Everything was fine until I moved to another flat.
In my new apartment, I have lost 3 transponders. I checked with my official decoder, it gives me all the channels and works quite well (even if the official decoder is plugged behind my VDRBox) so the signal should be OK.
In my city, there are 18 transponders. 15 are OK in my new flat, 3 are not…
First, I thought that the transponders were moved to other frequencies but some tests I did show me I was wrong.
Let me explain with a simple example: I lost this TP: Freq. 211.125MHz, SR 6875, INVERSION ON, FEC_AUTO.
I checked with 3 different drivers : - linux-dvb (08/11/2003) - dvb-kernel-1.1.1 - dvb-kernel-cvs (30/09/2004)
With the three different drivers, I can tune to any channel on an OK transponder With the three different drivers, I cannot tune to the TP FREQ 211.125 / SR 6875
When I look at the signal quality under VDR with femon, For all the available (good) transponders - the signal strength is around 100% - the signal / noise ratio is around 80% - 90% For all the other frequencies (lost transponders, 211.125) - the signal strength is around 60% - the signal / noise ratio is around 60%
There was just something weird I wasn’t able to reproduce but here is what I did:
- Scan TP 211.128 / SR 6875 - Nothing found (tuning failed) - Unload dvb-kernel-cvs driver - Load dvb-kernel-cvs driver - Scan TP 211.128 / SR 6875 - Every channel on this transponder was found !!! (-> the transponder is here !!) - Re-Scan of TP 211.128 / SR 6875 - Nothing found (tuning failed)
If anyone can give me a clue to solve this problem…
Thank you
Philippe
