/*
 * Initial mapping is for the TiVo remote included in the Nero LiquidTV bundle,
 * which also ships with a TiVo-branded IR transceiver, supported by the mceusb
 * driver. Note that the remote uses an NEC-ish protocol, but instead of having
 * a command/not_command pair, it has a vendor ID of 0x3085, but some keys, the
 * NEC extended checksums do pass, so the table presently has the intended
 * values and the checksum-passed versions for those keys.
