I have successfully made mp4 versions of my pte slide shows for many years and played them back on my 7 year old Sony KDL 46HX703 TV via memory sticks, but now I have found that the latest one I have made refuses to play the final 60 seconds of a 24 minute show! I don't think there is anything wrong with the slide show, which is made using the latest version of pte, and plays back from the same memory stick on my desktop without problem. This problem has not occurred with other, shorter, mp4s.
The TV has the latest software.
Any ideas, please?
