Hi,

My subtitles in Mediaportal go out of sync all the time. I use MPC_HC subtitle engine. On normal playback they are about 5 sec later and when I skip the subtitles are totally out of sync. When I use MPC-HC everything works flawless.

Any suggestions?

When I use directvobsub it works ok. But why doesn't MPC-HC subtitle engine?
