Hi again,
For completeness and reference for others I need to close this issue.
By comparing usbsnoop logs from Windows driver with source code of the
demod (dib7000p) I found out that the windows driver is using auto guard
interval when tuning. My channel configurations, tzap and MythTV, was
using manual guard interval at 1/8. After changing my configurations to
use auto guard interval I got 5:th mux working.
Now the card is back in duty ...
Merry Christmas,
/ Jyrki
