Hi,
I hope this is the correct place to post this question. I saw another topic that was similar. I purchased a URC3021 to use with my APEX gt2015dv TV/DVD combo. I am able to get most functions to work, but I am unable to change the video to input1 and input2 etc. I don't see a button specifically made for this, but I have done some reading and have heard some about discrete or advanced codes. Can one enter these on this universal remote, or have I cheated myself by going too cheap? Also, (and pardon my ignorance if this is a dumb question) I was wondering if there might be a way to cross-reference the signal I need with signals for other devices to find a substitute for this function. I would appreciate any and all help!

P.S. I know this is cheap and I could just go buy a remote with the correct functionality, but I'm a college student and dangit, I hate wasted money, lol.
