(I don't know if this sort of patch is welcome, but if it is I have a couple of other USB DVB sticks I will convert over as well. My main motivation was to be able to easily use a better remote than the mini one that comes with these devices.) This patch converts the dtt200u DVB USB driver over to the rc-core infrastructure for its handling of IR remotes. This device can receive generic NEC / NEC Extended signals and the switch to the newer core enables the easy use of tools such as ir-keytable to modify the active key map.
