DVD player and DVR issues

Ever since I switched to a DVR from a regular cable box, my DVD player no longer connects to the TV.  I have an old TV and use an RF Modulator.   I don't understand why the DVR became the problem, since all the connections were basically the same.  Any ideas about what to try? I had given up but want to try again.  Thanks.

You will need to describe your setup.  If your "old" TV is a CRT set, and doesn't even have compostie video in (which is why you are using the RF modulator), how are you selecting inputs?  Meaning, how do you change from (cable) TV to DVD?
