BDA driver issues with Pinnacle Dual DVB-T diversity stick

After exchanging my Pinnacle 200e DVB-T USB box for a Pinnacle 2001e Dual DVB-T diversity stick DD's BDA driver cannot tune to the VHF channels with 7 MHz bandwidth any more. All the channels with 8 MHz bandwidth work fine, but it looks like the bandwidth setting is not passed to the tuner.

If I do a rescan then only the 8 MHz channels are found, no matter if the bandwidth is set to 7 or even 6 MHz. The funny thing is that ScanMan's BDA_ALL driver does recognize the 7 MHz channels, but this driver has other issues. It recognizes 4 devices instead of only 2, and I have the feeling that it uses only tuner No. 1 no matter which of the 4 devices I activate. Which means that the diversity feature does not work with the BDA_ALL driver.

BTW I tested this with the current DD driver 2.1 as well as with the older version 1.1, but no difference. For the BDA_ALL driver I used all versions from 1.03 to 1.08, and they all behaved the same.

The stick uses a driver named mod7700.sys by a French company called DiBcom. AFAIK the other popular diversity stick TerraTec Cynergy uses the same driver, so this problem might apply to more people than just me.

Here is the BDA log file which shows how I first tune to a UHF station with 8 MHz bandwidth and then to a VHF station with 7 MHz bandwidth.
