I can be watching an IPTV source for hours no problem
next time I go to progdvb ( on windows 8 ) , I get a login window
If I leave it for a short time, then go to progdvb again it runs OK,
What triggers the login dialog box?
( Tried to add an attachment but !!! )

Windows login dialog or some ProgDVB dialog?

Is this something from Progdvb or the IPTV provider

Do you buy access to this channel and know login and password? Possible problem of auto reconnect function. Please send me log after next repeat.
