It's a fresh install. I have totally (with database in ProgramData...) uninstall the older. I thought too the problem was from a too big database and it's for this reason i deleted all.
Have you created your Mediaportal.log in debug mode (config set or watchdog Option? The log is not showing any Details why there are the long waits.
What kind of drives are disks E:/ and L:/ ?
I have used the watchdog with the action "Launch MediaPortal" and i proceed to a "report a bug to Team MediaPortal". E:/ and L:/ are virtual drives created by daemon tools
Really weird: loading of music, picture and video dll takes two min each.
Once you are through this: is MediaPortal behaving correctly or do you continue to experience slow response?
I have no real idea. The problem is clearly related to the shares, which makes me think of network issues. Can you try andf deactivate IPv6 in the network adapter settings?
I have found the solution... I desactivated IPV6 and was the same unfortunately. But during the reboot my gf wanted the MicroSD adaptor (without card) she let plugged on the rear panel yesterday... I tried it plugged without and it works like before. Sorry for the loose of time... Now i can rebuild my database...
