Mine looks the same, but it says "SMK" on the bottom.  Nothing
on the back.

My MCE kit WinTV-PVR-USB2 has a working IR receiver (but it is a very
old model).  The built-in IR receiver on the MCE kit does NOT work with
the MCE remote (RC5 vs RC6?).  The built-in IR receiver works with
lirc_i2c and the older WinTV-PVR-USB2 remotes (and about half of the
remotes that I have laying around my home).

The MCE remote works with the outboard beanbag transceiver (and it
works with an Xbox360).

If the info from this old driver version, pvrusb2-mci-20060121, is
missing something, let me know and I can get a copy of the logs from
the current driver version that I am running now.
