Hi. I have a HP laptop that uses a Pioneer DVR-K17 that doesn't have a digitally signed driver, which is fine, except when trying to install Itunes, it errors out saying - incomplete install. DVD driver not digitally signed. I have unistalled and reinstalled, no go. The only way to get around the driver error is to hit OK. But that doesn't fix it. I'm looking online and it looks as if alot of people have the same issue regarding finding the drivers.
