no video sequence header found" error & "no data, check your pids"
What does this mean? I am trying to convert to an itunes format (so mp4).
Is that the error message or what does it say exactly? And what are you doing anyway? You give no indication as to what your doing or trying to do? All you question is giving no specs or any lead as to what is going??? Just a reminder we don't mind read or read through the computer screen so if you want more help you have to provide sufficient information for us to go on.
Lets move you over to the General Software forum, but you may just need to create a new directory for the mp.4 file. try that.
