Jay,
I have the 15-1994 and the 3300 (code 0160). The advanced code for DVD input is 244. The sequence is:
-Device key
-P (two blinks)
-994
-P (one blink)
-244
-button to reside (3 and 8 are blank)
I'm not sure of the differences between the 1994 & 1995, I believe the 1995 can't "learn" from another remote. I can send other advanced codes for the 3300, including Video Select and a discrete Power Off, which were not on the original remote. There is a thread about the 1994 on Remote Central. Also check this FAQ:
