Hello, like some other users I am having problem with the preview window remaining blank. I just did a full deinstall of MediaPortal and then installed a fresh copy of just the TV Server v1.25 for now. I also installed the LAV Filters and raised the merit as was suggested with filmedit but still no success. Sounds works and helps in checking that the tuning is happening on a given channel but not as effective of course as having the video preview as well. Nothing special in the logs as far as I can tell. Anyone would have additional suggestions ? Would like to avoid having to rebuild the server from scratch.
