I have just bought Express Burn. The burnt DVD can be played on my PC, but also on my stand alone Bluray device, but not on my normal DVD. The normal DVD just shows the menu of the disc, but when I try to play a video it just stops. The DVD is burnt as a normal DVD (not Bluray). I have wasted some DVDs testing different options as DVD-R and DVD+R, slow burning speed and fast burning speed. I have also burnt DVDs with MPEG4 files as input but also with MPEG2 as input. Nothing works. My normal DVD is about 10 years old, but it has no problems playing commercial DVDs, old as well as new.
