[QUOTE="doveman, post: 710674, member: 67412"] What I meant was would it cause problems for any users if MP automatically refreshed the EPG after each scan. If not, it seems it would make sense to do that, rather than make the user find and click on the Refresh EPG button. It seems not uncommon for channels on Freeview to get replaced by others and when that happens it seems the EPG data will be wrong unless it is refreshed. I think it's a different problem, but for the last couple of days, my EPG has been showing "Channel One is no longer broadcasting" for that channel. I looked it up on the web and it says that Channel One has been replace by Challenge, so I did a scan and it picked up Challenge, but didn't delete Channel One. Looking at the details it shows the following for Challenge: Channel: 46 Frequency: 562000 NetworkId: 9018 TransportId: 12290 ServiceId: 15520 Bandwidth: 8Mhz PmtPid: 395 Provider: BSkyB whereas Channel One is: Channel 20 Frequency: 562000 NetworkId: 9018 TransportId: 12290 ServiceId: 14304 Bandwidth: 8Mhz PmtPid: 273 Provider: Virgin Media As you can see, even though they say that Challenge replaces Channel One, they have different details, which means that MP doesn't realise it's a replacement and thinks it's a new channel and leaves Channel One in the list. I just deleted Channel One manually and did another scan and it didn't pick it up again, so it doesn't appear to be broadcasting anymore, so surely MP should be able to detect this and delete it. If there's some reason why it can't do this, perhaps MP could delete the channel list before scanning (after making a temporary backup to compare with afterwards) which should avoid redundant channels being left in the list.
