Well I am running a SVn in the earl 98xx range, and what you describe 
fits my results to a T. Unfortunately, I have no cable at the office, 
nor DSL at home, so I cannot do a scan here. So mythfill downloaded the 
program data for the entire 506 channel universe!

I have since purged down the channel list. It was actually easier to do 
it in mysql than in mythtv-setup.
