Attached is the firmware for the "LifeView TV Walker Twin" (01fd:0514)

7119b154e7975a7fc2d5cb7c4bed5b28 dvb-usb-lifeview-tv-walker-twin-0.95-20051010.bin

... as reconstructed from a dump of the usb transactions sent by
windows with the M9207BDA.sys driver loaded. However it's possible
that M9207BDA.sys contains more than one firmware.

This is the diff between the firmware reported by Pierre Willenbrock
and mine:

5,8c5,8

The differences are:

byte  0106  f6 -> 91  (load address??)
byte  0127  15 -> 05  (this is the LSB of the PID after firmware download)
byte  0140  00 -> 01  (no idea)
byte  0166  08 -> 05  (length of the following device name string)
bytes 0167 - 0176     (different device name)

What are the first two bytes of every chunk in the firmware file
(the "value")?

Nick.
