DVD burner or DVD player's fault?

Hi.
I burned two movies on DVD-RW's, and watched them on my DVD player hooked up to my TV.
First movie, the quality is not so nice, and towards the middle at some places it started to slow down the movie up to the point of 1 fps plus the image got splattered all over the place and then it just skipped right to the end of the movie.
Second movie played no problem, and again the quality wasn't perfect but then at the mid of the movie it stopped playing it and I couldnt "skip" to next chapter, "fastforward", "play", "pause" and "play".

But when I put the dvd movies in my PC's new LG drive with upgraded firmware, and went into the VIDEO_TS folder, using VLC player opened and played on the parts I had problems with while watching it on my dvd player, and everything was perfect, no slow downs or freezes. And quality was nice, but maybe because I played it on 17" monitor instead of 32" tv set.

So is it my dvd player's fault, playing movies so badly or dvd burner's for burning it incorrectly?
Note, my dvd player is Toshiba, and it is in-car dvd player, not like home stand alone dvd player.

Thx

1) why are you using dvd-rw? Your dedicated dvd player might read plain DVD-+Rs better.

2) depending on the software, you are losing quote a bit of data when copying movies. That is unavoidable, but your dvd player can't handle it. You may need to adjust quality settings.

all in all, i'd blame the dvd player more than I would your computer.

I have no end of problems trying to play certain DVD-/+/RW's on standalone dvd players. I usually have to find one that's compatible with the player and stick with it. They can be very fussy and older ones won't recognize more recent dvd types at all.

So, which is better DVD-R or DVD+R for burning movies that are to be played on standalone, dedicated DVD players?

It varies from player to player and by media manufacturer. The only way is to test your drive with different types of discs. There is no silver bullet.
