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 ...
