I carn't seem to program my toshiba tv remote to work my toshiba dvd player

Instructions for your TV will tell you how to program your remote.
One of these codes should work.

Just buy one universal remote control which have set up codes for Toshiba, or an orginal one from the authorised service center for Toshiba.

You should use the component video input (which ever the TV has), you will get better pictures than the S-video.
As far as the remote control for the DVD, keep using the one that comes with your DVD player, Comcast remote does not always work, beside you get full function using the DVD's remote, that is how I use my DVD, same for the TV, Comcast remote my not be able to send out the signals to the ATV for selecting the input sources on the TV. Comcast remote is not a full functions remote.

The remote code 0142 worked for my Toshiba MD13P1.

code list for philips remote for my toshiba TV

I had the same problem, and the solution above/below that says to use code 018 worked for me. Yeah!!!

I can't exactly help you, but can you tell me how you programmed the remote to your TV, because I cannot get mine to work...

Easiest way is to do a search all codes. Majority of DVD players are rebranded from a few major makers, even SONY and Toshiba, etc.

Probably only as long as it's a Toshiba dvd player, can't say i've ever got one to work even the TV hansets with dvd controls. This is what the site says it works with:- This replacement remote will operate all functions of models 32A33, 32A43, 32AF43, 32AF44, 35AF44, 35A44, 36A43 and 36AF43.
