Having problems, playing a burned DVD+R on my HD-DVD player..?

Hi there.

I have a Toshiba HD-A30KU HD-DVD player, So what I would like to do is burn a DVD movie using TDK DVD+R 4.7gb. but the message on my dvd player says "check the disk".. So what I would like to know is what do I need in order to view my burned DVD's on my dvd player???
And what software should I use to burn a movie onto my DVD

Please help!!!
