Please provide some information about the hard- and software used.

Box type: 7025
GUI (enigma2) LT3
Single dish, two twin LNB:s set at Thor (0.9W) and Sirius (5W).

My question

Two months ago I bought a new DB 7025 with a samsung HD and Two twin
Lnb, two 2:1 diseq, and has now two cables from the disc to the
dreambox. For some reason I can not record one programe and watch
another program (comes from the same sattellite, Astra/Sirius). When i
record and then switch to another programe it just says "Tunning cannot be done"
I have eliminated all possibilites of the problem being from, antenna
cabel, diseq, Lnb and so on. The only thing that is left, is that one
of the Tuner slots must be inactive/broken. The slot that does not
seams to work is the one closer to the hard drive (the middle of the box).

Further th signal strength at tuner B is always to low (no "lock") on Sirius but good enough on Thor (but even so no getting "tuning failure" on both sats if Tuner A is dissconnected.

I have even switched the tuners and still "tuning failure" on Tuner B???

I have also tried both autom. and manuell scanning, no luck on either.

Any ideas guys??
