Maybe RTL codes the sequence for some strange reason that way, that exactly 1 picture after the 16:9/4:3 switch a new one begins... or they have an off-one-bug... hmmm, NO... it is not possible that a sequence can contain both 4:3 and 16:9 frames! Per definition... So,... do we maybe have an off-by-one bug which causes displaying one picture with a wrong aspect ratio? BTW,...the real commercial breaks are indeed about 12(18)/2 frames away from the AR change (and the marker lies at +1 frame from that position)... > > > Maybe even the DVD-player refuses to work...

Of course,... and the letterbox bars which have to be added (for a 4:3 TV)... ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
