We already created a ticket,but maybe this forum could bring us the solution we are searching for! When we set the PC back in a earlier time ( two weeks, and everything was ok,just before creating the back-up), the problem still exists!! Looks like an internet-problem,doesnt it?? When downloading a YouTube-url from the YouTube-mainscreen in PowerDVD12,with YouTubeDownloader, we get a flv-file wich we can play in PowerDVD12,so this file-type is no problem. It looks like PowerDVD12 can not download the file you have chosen,or it can not play this file for some reason??!
Do NOT GIVE UP!! CyberLink updates PDVD12 next month for solving these frustrating problem!!
