[QUOTE="CyberSimian, post: 1290513, member: 141969"] I have also noticed this for a long time with my own skin (so not just the DWHD skin). But I also think that I know the cause (at least in my case). When I first started using MP (in 2014), I setup the EPG grabbing in such a way that TV Server grabbed the EPG very frequently. And I noticed the missing red dots at apparently random times. I now realise that TV Server was grabbing the EPG at these times, and [b]updating the SQL database[/b]. I now grab the EPG only once per day (06:00 to 06:30), and I never notice missing red dots [i]unless[/i] I view the EPG or the Scheduler during this time. So in my case I am reasonably sure that the problem is contention for the SQL database. If the EPG grabber is updating the database, it prevents the MP Client being able to query the database to determine if red dots should be displayed on the screen. There must be a timeout for the query, since you do see the EPG or Scheduler panel, but without the red dots. The EPG that I use is the EPG that is broadcast embedded within the DVB-T signals. In the UK it takes around 10-15 minutes to extract the complete EPG from the broadcast datastream, and then another 15 minutes to update the database. So there is this 15-minute window during which the red dots may be missing. Having unreliable red dots is [i]definitely[/i] not desirable, but I am not a database expert, so I don't know whether it would be possible to redesign the database access to avoid the missing red dots. And even if it is possible, there is no one available to implement such changes. :( -- from CyberSimian in the UK [/QUOTE]
