Dvd burer not working

[qanda]This thread is about the Acer AcerMedia CD-RW module. Click here to see full specs[/qanda]my problem is that when I burn a movie using convertx to dvd it tells me that the burn is complete,but my computer shows nothing on the disc after burn.The disc it’s self looks like it has been burnt,but computer or other dvd players show nothing but empty compliant.This always worked in the past wondering if it might be a software problem,and each time I put in a blank disc to burn it wants to know if I want to format it.
Any help would be greatly appreciated Thanks.
