OK...I may be missing something, but it seems to me that interactive
is potentially the wrong solution.  In my area, VOD is -always- on the
same channels, and the sequence (down, left, enter, up,
enter...whatever...) is -always- the same.  This means that anytime
I'm tuning to channel one (for example), I need to enter the channel
number, wait 3 seconds, send down, left, enter, wait two seconds, send
up, enter.  If this is the case, then you simply need to modify the
script that changes channels to be a tad smarter, something like this
pseudocode:

<change channel to> channel

if (channel == 1) then
  irsend <some extra codes>
fi

With this approach, the fact that you're watching VOD becomes
invisible, you're doing it on the backend and have all the information
necessary, etc, etc, etc.
