I have a Liton drive model iHAS42208-8 22X which will NOT BURN. I have VISTA 64. I have called Liteon followed their instructions regarding the registry, they said it will deffinately work for vista 64. IT DID NOT! I've tried everything, DVD+R/RW, DVD+RW - NOTHING WORKS. The drive actually burns the disk (you can see on the disk it burned) but will not play on TV. I have software Xilisoft avi to dvd, AnyVideo converter, AVS Video converter (which does not tell you how to burn even though the web-site says it burns). and then when I use Xilisoft avi to dvd it tells me I have the wrong kind of disc! don't know what else to do. HELP!!!
