[mythtv] Previously recorded programs question

[Panix]

While working on the MythWeb conflicts additions I made, I came across an 
interesting question.  Why are you not able to record a program that was 
previously recorded if the file does not exist on your system anymore?

I can understand not recording the program again if the program was still 
available on your system, but if you delete the program, you should get the 
ability to record it again.

My proposal: Change the code that checks for this to also check to see if the 
program exists in the recorded database table as well as the oldrecorded 
table.

I have working code in place for MythWeb that checks for this, but the 
frontend doesnt check for this so I have it commented out for now, since I 
want both the frontend and MythWeb to behave the same way.
