Hi,
I have a Time Warner Cable universal that came with my HD cable box. I have successfully setup my TV and cable box, but am having a bear of a time with my Durabrand DVD player. I went so far as to research Durabrand (somewhat) and found some of the manufacturing companies. There were 3 companies listed that do not have codes in the DVD section of my universal manual (Orion, Maxell, Resonance) but I DID try the others which I will list below:
Lenoxx
Funai
Emerson
Sylvania
Initial Technoloigies
I'm running out of options here! ;) Perhaps I'll just have to settle for using 2 remotes, but I'm hoping someone here has either a) another company I can try or b) the magic 4 digit code I need. Thanks and take care!

Presumably you got your information from here?

Unfortunately it would seem there's a myriad of different companies involved, so unless they've all used the same code set, or you know the exact manufacturer (some of which you already know are not supported anyway), I can only suggest you purchase either a low cost (recognised manufacturer) player or learning remote. Then again you could, as you suggest, make do with the two remotes.
