Compatibility of DVD±RW

[Booooom]

Hello,
I have a Graetz AV-290 dvd player and I need to find a competible DVD±RW. So far I have tried the following DVD±RWs:
Memorex. My DVD wasn't able to read any of them.
I am using Nec DVD burner ND-3520A.

1. Does anyone of you know of any compatible either DVD+RW or DVD-RW to this DVD?
2. I have burnt my vidoes using NeroVisionExpress ver.3.0.1.4. is there any relevance to that, i.e. had I have used a different authoring program, my DVD would have been able to read the RWs?
3. I have used Winxp build-in drivers for my burner, is there a point updating the drivers?

Thanks

Why not just use DVD-R or +R? The discs are cheaper and have higher compatiblity with players.

True enough, and I do that all the time, although I am facing with yet another funny program where I can only Fast-Forward x2 and no rewind at all (movie gets stuck and I have to press Stop than Play to replay the movie) on my DVD-R, but that's probably because I use NeroVisionExpress.
I want to figure out which are the compatible DVD±RWs and have a stock of 2-3 of those.

Thanks.

If the player doesn't even work right with DVD-R discs, I doubt it will play RWs.
