I've been using DVD Shrink very successfully for awhile now, ever since getting advice on these forums to use Verbatim for my burning medium. Suddenly, whenever I put a DVD into my burner and start up DVD Shrink to copy it, DVD Shrink tells me that there is no disc in the drive. I have not updated any software on this computer or changed my computer's configuration at all prior to getting this error, so I'm perplexed as to why DVD Shrink cannot seem to read a disc from my DVD drive. I'm using a LiteOn 56x DVD burner (cost about 65 dollars), and Verbatim DVDs. I've successfully burned hundreds of movies, but suddenly DVD Shrink tells me there is no disc in the drive. Any help or information would be greatly appreciated. Thanks.
