Was curious if anyone here might know whats going on with Intervideo ---

My friends told me its a great way to convert movies -- so I got it to try out ...

Tried it 3 times now .. first two times I let it burn the DVD for me --- It SEEMED to work perfect but the dvds wouldnt play anywhere.. the DVD player didnt recocognize and either did my computer ---

So third time I had it just make the files on my computer ---
this time it gave me vob files but they were only 300k big .. i mean ummm DVD shoulda been close to 4 gigs...

so I have no idea whats going on here...

any help is greatly appreciated
