The only media I use and have been using for at least three years is RIDATA DVD+R, I have never had a problem with any disk playing on any of my players. This Slideshow disk I made will only play using the Roxio DVD player on my computer. It plays just as planned there. Windows does not even recognize the file, it tells me it is a file that Windows does not use. I have no way to tell if it burned as an >avi file or not. I can say that it took about an hour or more to process and then only took up a very small space on the disk. I've burnt 3 disks and all have the same problem. I followed all the instructions for making the DVD and it makes me wonder if the disk is finalized. I tried to finalize it again but the program will not do it. I finally gave up and used a ULEAD program I have had for years and it worked perfectly. I'm disappointed that everyone seems to be having a problem and all the help we get is "try new media" ot "try another DVD player". It has to be a problem with the program. Not everyone has burning problems. Like I said I've upgraded the drivers for both my burner and video card.
