Yes!  I do this all the time, busy watching live tv but delayed by maybe 
20 or 30 minutes because I paused for a while, ad break comes on, I 
forget I'm watching delayed TV and hit the channel up button to surf 
while the ads are on, as soon as I've hit the button I realise I've just 
ost 20mins of whatever I was watching. ARGH!

That's one solution, but I think a better one would be if you are 
currently watching with a delay that if you do anything that would lose 
the delayed video (change channels, ESC, etc) it should prompt you first 
.. "You are watching live tv delayed by x minutes, are you sure you want 
to do this ?".  I doubt would remember to hit the L key to lock a channel.
