It's probably worth finding out which channels are missing and having
a look here

to see if it's a particular multiplex that you've lost.  Sometimes you
can force the scan to find a particular multiplex my entering the
frequency and mode paramaters manually.

Are both your cards configured to use the same source?  I'd have
thought that they should be, unless you have decryption on one of them
giving you more channels.

If they are both using the same source then presumably it's a signal
quality issue and one card is working better than the other.  Have you
tried swapping your input cables over?

I'm not sure why a signal quality issue would suddenly bite you but
maybe some channels have moved around and there's now some
interference on channels you'd like to watch.
