Making a DVD with Windows DVD Maker?

Well the thing is, I've taken videos from my Nikon camera, converted them and made a little film with them using Windows Movie Maker. This little film was then published and encoding began on a blank disc with Windows DVD Maker which took no longer than 15 minutes before it said the disc was done and ejected it. I've just put the DVD back into my laptop to play and my computer only acknowledges it as a blank disc which is puzzling me. Could anyone help me out or let me know where I'm going wrong. Thank you.

Extras - My laptop is an Advent with Windows Vista.

Burn it with Power ISO

I think the best DVD creator is convertXtoDVDs, it is able to burn any video and movie in all media type to DVD-5 and DVD-9, make the DVD playable on DVD player.
You also can create DVD Menu and add subtitles(SRT, .SUB/IDX, .SSA) to DVD Videos with VSO ConvertXtoDVD. It can create NTSC DVD and PAL DVD with high quality.
