i use the pocket dvd studio software. when i first got it it worked great. then i upgraded to newest version. it would not work. it acted like it was recording the dvd but then when it was finished it was a file of only 32kb's. i sent an email to support last week but never heard anything from them. i saw on their website that if you are having problems with current version then download the 1.2.6 version. i did and it works great. try that.here is the link:
