pulling my hair out

have a pioneer a04 running windows xp. using dvd workshop and burning to disk after creating menus etc and the resulting dvd works perfectly. however if i save the iso within workshop and try burning that to disk within workshop i get all manner of probs. they range from sync problems to movies playing to halfway point then freezing to not working at all.
have also tried using the audio and video directories and nero 5.5.90 and get same probs. is this an issue with my writer or dvd workshop.

Can you make an ISO of the disk you made ?

is DVD Workshop patched? Andhow have you tested your image file, What i do is have DVd Workshop make the vob files, thne i load thm up in Power DVD and se if it plays back, if it does then I know it's allright. All of my synch problem with Ulead products ( DVD Movie Factory and DVD Workshop were solved once they were patched , note the patches do not work on demos). I still use Nero for my burns and no the Ulead burning engine.
