Remote codes for the LD-V4300D/LD-V4400 players
Each file contains a list of buttons and what 32-bit number they transmit.
All buttons on the remotes are sent using the NEC encoding, other than the volume up/down keys. See also: documentation of how it's encoded
Those keys are encoded using some other protocol that I haven't identified, so they are not filled out.
The setup from this article was used, with an Arduino Uno and a generic IRC receiver. This uses the Arduino-IRremote library to decode the values received.
