Sounds like you're not getting all the multiplexes. You might try 
scanning again, might be a weather-related problem. If that doesn't 
work, consider if your aerial is good enough, or that it is aligned for 
best signal. If you have a signal booster lying around try inserting 
that, may make some difference. (An older booster designed for analogue 
may not boost all channels equally, more important for digital sources). 
Until the analogue signal gets switched off digital signals are 
transmitted at reduced strength, which can be a pain if you are in a 
marginal area.

Another option is to use the dvb-utils tools to run a scan. This will 
provide you with a whole bunch of diagnostic info to help you determine 
what you can/cant/might only just be able to receive, and what you might 
do to fix the problem.
