I've been burning dvd's for a while using ConvertXtodvd for the last couple yrs with no problems. I use either Verbatim or Sony blank dvd's...again, with no problems. Now, for the past few months, my dvd's have been freezing up in my dvd player. Originally I thought it was the player (because it's old) so I bought a new Sony DVD Player, to my surprise, that doesn't seem to be the case because it's still doing it. I have slowed down the rate speed to 4x and even used my external dvd burner and they still freeze up. But when I put the same dvd in my laptop, it plays perfectly. And when I put an older burned dvd in the Sony player, it's perfect. So it's not the dvd player or the dvd media. I'm not a computer expert and for the life of me, cannot figure out what could have changed in the last few months to make this happen. I've recently downloaded Linux but still have windows installed for my burning. However, since I've been using Linux, I haven't done a Windows Update, could this have anything to do with it? I'M BAFFLED!
