As soon as the EPG scan kicks in, this will be lost again.
So I don't see where this would be of any help.

As Tilo Renkl posted recently, he even has the problem on a single card
system, without any recording, CAM or transfer mode. So I'm afraid the
UPT problem has nothing to do with the things you have patched here.
Of course, I'll stand corrected if any of those actually having the UPT
problem proves that your patch does fix it.

Maybe these things should be tested _before_ applying your patch.
