I have tried all the discrete input hex codes I can find from Remote central and personal ccf uploads. There appears to be a unique IR code for the DVD component video input for a Mitsubishi VS45605. There may not be one at all. If anyone has a lead on this or suggestions on how to modify hex to try something, or someone who might be able to find the code, i would appreciate ANY ideas as I am at the end of my rope for possible sources.

Check out the thread below from hometheaterspot.com - especially the post by Fat Bob that tells you how to set your factory remote to send out discrete codes so you can program your pronto.

From thread:

Press and hold the POWER button, and while holding the power button enter 090.

Now the remote functions like this:

Pressing INPUT followed by:

When done, press and hold the POWER button and enter code 000"
