Unreliable results using Vison Express 3 to make dvd'd

I make photo stories in Microsoft PS3, generate a .wmv file PAL 1024x768 then transcode it and burn it in VE3, onto a DVD-R. Results variable: 3 times out of 4 I get a video which zips through my Pioneer player like a machine gun, without transitions. :confused: Yet I set every project up in precisely the same way, use the same Fujifilm dvd’s… AND often but not always, the video will play correctly in WMP10! I always close down all active programmes, screen-saver, the lot, before starting to transcode and burn. All suggestions welcome!
