As I wrote before, the old driver ignores the 3 upper address bits.
There are 5 address bits = 32 possible values for the -a option (0..31).
If your codes were in the range 0x40..0x7f, the correct values for 
-a might be 1,5,9,13,17,21,25 or 29.

You have to fix your keymap, too:
All codes must be in the range 0..0x3f:
- For old codes 0x40..0x7f, subtract 0x40.
- For old codes 0x80..0xbf, subtract 0x80.
- For old codes 0xc0..0xff, subtract 0xc0.

See above. If nothing helps, enable debugging in the driver (add option 
'av7110_ir_debug=1' when loading dvb-ttpci.o) and check the debug 
output: 'addr' is the address value sent by the transmitter.

Looks ok.

This cannot work.

I think it will work if you fix your keymap and specify the correct 
address value.
