Hifi-remote.com has a file for your player. Several remotes made by UEI will work. The best fit is the RCA RCRP05B ($20 at Walgreeens or Best Buy) using setup code DVD 0830. The Menu button will bring up the DVD menu. To get the TV menu to also work, you could assign a 5 digit EFC to, for example, the Guide button.
You would
1) Tap DVD
2) Press Setup until 2 blinks
3) Enter 994
4) Tap Setup
5) Enter 00235 (this is the EFC)
6) Tap Guide (or some other button of your choosing)
Now tapping Guide will bring up the TV menu.

Some OneForAll remotes will also work, but will require more manual programming to assign additional EFCs.
