Where can I find codes for my universal remote?

[Winchester]

I need the code for an Apex DVD player to program it in my universal remote. I have a Sony RM-V401. Anyone know where I can find the codes. Apex is not on the included sheet and I tried all the DVD codes.

I found this but it doesn't list Apex. http://www.xdiv.com/remotes/sony_rm-v301.html Try contacting Sony directly?
