JWF,

Can't find the RCA codes, but the codes for your Sony DVD player and the Yamaha LaserDisc player are available in the Pronto file section. You can download the ProntoEdit application, load these libraries, display the Pronto Hex codes for each command, and cut and paste them into your T2 library one by one. A bit tedious, but it does the trick. Search this forum for more detailed descriptions of this procedure.
