SOURCE: Code Number for Remote Programming

Here is the link for the 8300 user manual if you need it; http://www.cox.com/support/digitalcable/dvr/pdf/SA8300HD%20connects.pdf here is manual for the dvd player http://www.yamakawa.it/dload/2xxenglish.pdf Not sure but try 438 or 445 as a code for your dvd, 445 most likely to work. (here is the link i got that from); http://dogbytecomputer.com/codes.htm#DVD%20CODES if this doesn't work then find a universal remote that you can get hold of easily near you and tell us the model number, we could probably tell you if it will be compatible with both machines and what the codes are. Hope this helps :)

Don't know the exact code for your STB, but you can download the manual from http://www.yamaha.com/yec/products/productdetail.html?CNTID=5027893&CTID=5000300&RLTID=1505&DETYP=RELATION ,
There you can find the list of all codes and also how to program them into the remote.
