Should work.
I just happen to be working on a VOD Playlist and find myself loading and reloading the Playlist onto Perfect Player (as I edit and go along arranging the channels on the List).
Have not had an issue with playing after loading, except only once when I did not have the URL and the password correct in each channel line.
Are you using the USB or URL method with Playlist ?
okay, but if you wanna try again, open that m3u Playlist with Wordpad or Notepad and look at the a VOD movies channel line.
The server URL should be there and then your User and Pass should be showing there too.

abc = server URL (the prefix http:// is already there, so do not add that again).
xyz = user and pass code
