Sadly we would need a lot more information to help you, would be great if you could follow the post logs instructions in my signature and upload using the forum advanced + feature.
Hi,
sorry for your time. I understand that you need more information to help me.
I upgraded from 1.1.0 to 1.2.1 and after upgrade I instaled windows xp sp3. There is somewhere reason why this problem happened.
So eventually I removed completely mediaportal and installed clean 1.2.1 version. Now everything works as it used to do for so many previous years.
P.S. This trend with video list with aprox 8-10 list items is so wrong. I have huge tv and list uses only 1/6 to 1/4 of available space. I do use plugins for specific type of media, but eventually I need to browse through the list.
