I have burnt my first film to a DVD-RW using DVD Shrink and Nero.

The film plays perfectly in my standalone DVD player, but when I put it back in the PC it won't play, and I can't access any of the files with explorer.

I want to try and put in on DVD-R, and unfortunately, have already deleted it from the hard drive.

Any suggestions guys.

This is reading it with the same drive that burnt it?

Yes its a pioneer A105. Also tried to read it in Sony DVD Rom

What kind of DVD-RW is it? I have a cheap generic DVD-RW which won't read in anything but my 105 and occasionally it won't boot up in there either. Also which program are you using to read the DVD-RW with?

What Operating System are you using and did you burn it in "multi session" mode ?.
If you did and you are not using Windows XP, it's possible that you wont be able to read it back in, on a non Windows XP PC.
