As *steve* said.
If you intend to do this often, ensure your recorder (burner) format is compatible with
your play-back device.
There may be programs to compensate for what you did in this case, but I don't know.
I use Sony and Toshiba actual DVD recorders, not a computer. They play back on
everything I have, including the computer. As a side-note, if you consider this, as a
few people found-out in posts here previously. If you use a DVD recorder, you MUST,
'finalize the disc', or it won't play back on anything except the original recorder you used to burn the disc in the first place.
I'm wondering if anybody else here ever heard of software commercailly available to
convert incompatible formats, or if once you record in one, you're stuck with it.
