Help please!
Embedded video and audio content in PDFs created using Adobe Acrobat X Pro does NOT play on some school computers after Acrobat Reader XI is installed. The media content played fine with Acrobat X. This is seen with both XP and Windows 7 machines.
Bizarrely, other machines with Windows 7 and XP play the video and audio content fine when Acrobat XI is installed.
Please help, as the PDFs are the delivery mechanism for a very effective literacy programme for children, and this bug has halted delivery for a considerable number of schools and thousands of children are in trouble!
