This is a small check list to verify what might went wrong if your DVD-R doesn't play in your settop player.
Did you rip ALL files in original format to your HD ?
Is the folder 'VIDEO_TS' existing, and is it uppercase ?
Is the DVD-R project playable with IfoEdit's DVD Player, or Matrox DVD Player ?
Have you used 'Get VTS Sectors' on all IFO files, right before burning it to DVD-R ?
Have you re-started IfoEdit before you've used 'Get VTS Sectors' ?
Have you created an image with IfoEdit's image creation button ?
burned the image with an other tool then Nero ?
If you didn't used IfoEdit's image creation button:
used UDF 1.02 and ISO filesystem when burning the DVD-R.
