There probably isn't going to be a lot of need for the converter box to be operated by the satellite remote. The DTV PAL (TR40 by Echosphere) has the greatest odds of having a code. Zenith/Magnavox/RCA DTV boxes will also have a chance that another code for some other product of theirs will turn on and off and change channels on their box.
Sorry that you have been so misinformed if DISH delivers your locals today they will deliver them on Feb.18,2009 just like they do today.
It won't hurt to have the additional capabilities for your Toshiba but it isn't really necessary.
