There are limits imposed by apache on how many fields can be passed back at any 
one time. If you have enough channels defined it is easy to blow those limits. 
If you look at your apache logs you'll be able to verify this.

I can't remember offhand which particular apache file the limits are in or what 
needs increasing but they are relatively easy to find. There's also something 
called "suhosin" which has yet more limits which apply to php execution. Look 
for those files also.

An alternative approach would be to use the editing facilities in mythtv-setup, 
of course, although that can get tedious if you have a lot of channels to do.
