Can I do this?

I've got my sony cd changed connected to my amp using a digital cable. This is mainly so I can play my dts cd. My amp (yamaha dsp-a1) has a 'feature' in that once it's switched to dts mode, it doesn't switch out again unless you press a button on the remote.

Is there anyway I can setup slink-e to send that IR signal once it's finished playing a dts cd (I have dts in the keyword field).

For extra credit, can I switch the amp into dts mode when the cd plays too (it does it automatically, but it plays just noise for 0.3 seconds and this can be quite loud).
