Some of the 1025 cards have been very nasty. It resembles an older
case where one card would not tune to either vertical (or was it
Horizontal) completely stuck at one volytage level.
To take a bite at it, load the dst module with verbose=5, module
parameter. look at the logs, if you have timing errors you will see
them in the log.

just post the logs, will take in a look whether anything's possible.
