Theres a issue with two last versions of Progdvb, it is changing itself to the letterbox screen (in options, video, geometry), so you have to reset manually to "none" to correct video aspect..
PS. I always thoght "letterbox" was reducing picture and putting side black bars, but in Progdvb it means expanding picture, so you may loose lot of image portions (bye-bye logos).
PS2. A question to Prog: I have some channels that change a lot aspect ratio of picture, but Progdvb keeps fixed, so people is fat-thin-fat...
Is this a source issue or Progdvb is not updating picture aspect info in auto mode?
I will try to discover this, will make some records and run in other players...
