Making videos "for sure" playable in standalone player

[Meagain]

Hello all, I know I have put this question, more or less, before to this forum. But I persist, because last time I was recommended DVD Flick, which is fine I suppose, but some resulting DVD's won't play in e.g. Nero ShowTime but will play in Power DVD, some will play in VLC Media Player but not in WinDVD - all will play fine, however, in the itty-bitty KMPlayer, no problem...go figure!
See, here's what I want to do: convert .avi-files to DVD format, add subs if any, preferably burn directly to the blank DVD and finally be confident it will play in my friends standalone DVD players. There it is.
Oh, yes, one more thing: does it matter, as far as subsequent 'readability' goes if its a rewritable disc or a straight R?

Thank you!
