Topfield 5800/Troubleshooting/EPG Duplicates
Due to bugs in the EPG data collection, if the Toppy is left on for a long time it will run out of free slots for new data and there may be gaps, duplicate entries or whole missing channels. Currently, the simplest solution is to regularly switch the Toppy into standby (which helps save electricity, too). (Previous concerns about missing recordings when in standby have been addressed by fixes to the Timers Bug.)
