DVDs have 2 formats, NTSC and PAL. NTSC is for North America and PAL is everyone else. You can play PAL DVDs on your PC because the players are made to convert either format, however a DVD player made for NTSC wouldn't play a PAL-formatted DVD. There's software out there that states it can convert PAL to NTSC but so far any test subjects I've done with them have been failures (They'll play okay as long as the camera is still but as soon as it pans out or moves the picture becomes choppy). There are a few DVD players out there that'll play both formats but they're limited and pretty costly.
CowboyChris - Were you trying to burn the media as a DVD-format or were you simply burning them as data? If you burn it as data it's the same as if you were burning normal files, mp3s, etc on a cd (Only now you're doing it to a DVD). I also have a 16x and it normally takes 5-10 minutes to burn.
- Now, if you're burning it as a DVD-format than here's where the length comes from. Nero (Or any other software) has to encode the files to where it can play on a DVD format (DVD format is encrypted with css), assuming you're using the full DVD space this normally takes 1 1/2 hours - 2 hours. Assuming you picked this mode: 2 hours to encode, 5-10 minutes to burn.
Try this next time Start, Programs, Nero, Data, Nero Express (Then when it comes up - Data, Data DVD. Add your files then burn). It won't play on your DVD player but will work on a PC. Hope this helps...
