Does your set-top dvd player have the ability to play dvd-/+ rw's? If yes then why not trial them out. I don't know about the uk, but here we can watch either pal/ntsc without issues. But in some countries it's not so easy! You may need to convert them to pal during the conversion process. ie: in your settings make sure you check pal.

Also keep in mind you can't have both ntsc & pal video files together. The settings must be one or the other. Complex is the other option (which would mean having one version in pal & the other in ntsc - not worth the waste of space of the disk! 2 of the same movie.)

Make sure you burn your disks at minimum speed! OK so it takes longer, but it will be more reliable.

To be honest, I've never heard of your brand of media. Why not try another brand. Verbatim is a reliable brand. There's others also but I can't think of their names off hand. It depends very much on what's available in your area.

If you're burning a DVD- disk make sure you finalise the disk! (comparison to dvd+ disks which don't need to be finalised.) Make sure your player can play that brand AND that type; ie: dvd- or dvd+
