Compatibility Mystery

[alegator]

I use two types of DVD media to play in my home DVD player: Verbatim DVD+RW5 and Prodisc DVD-R5. I also use NERO BURNING ROM to burn the DVD's.
I just burned a movie onto a Prodisc and the home player did not recognize it. So I copied the same movie onto the Verbatim, it didn't play either. Yet the PC recognizes and plays both DVD's.
NERO Burning ROM does not report any conflict in the files and says the burning process was successful.
I use the latest version 6.6 but I used the previous version 6.3 before,
Could it be the latest version not working well? Or could it be the file structure of the movie? (again Nero does not report any conflict while burning)
Thanks for your reply.

If the only thing that has changed is nero, I would start with that as the main suspect. If possible, install the earlier version and see if things go back to normal

I was able to play in the home player a DVD burned with Nero 6.6, so that's not the issue....
what else could it be?

[glockjs]

have u ever played a burnt disc on this player?

what programs did you use to make the dvd....what steps did you take?

need more details

I use Nero Burning ROM versions 6.3 and now 6.6 (the latest as I always update with latest patches). I burned both DVD+RW's and DVD-R's and never had an issua until I found now. I tested DVD+RW's and DVD-R's that I burned both with 6.3 and 6.6 and some play and some don't. I just can't find an explanation to this other than something related to the original movie files?
One more thing, ALL of these DVD's are playable in my PC with Cyberlink PowerDVD player.

PowerDVD is not a great test of compatbility or compliance, as it will play pretty much anything vaguely DVD-ish

[alegator]

So what software do you suggest to test compliance?

Well, I just finished a spindle of +R and I went to BestBuy and bought a spindle of -R, because it was 19.99 (Fuji). Tried them in my standalone Sony and no go. The +R works fine though.

I think your standalone isn't liking the -R discs if you've used +R before.

But I can play some of the -R DVD's I burned eventhoug all of the -R's I have are the same brand/type!

[guns1inger]

Because of the vaguries of the manufacturing process for blank disks, the quality of DVD burners, and the polar tilt of the earth, there is no way you can guarrantee you will get perfect burns on every disk in a spindle, regardless of brand. Better brands usually mean higher probabilitiy of more better burns, but even the best will fail sometimes.

But what you describe should be a statistically low effect. IN my case, almost ALL of the DVD-R Prodisc I burned at 4X are not readable with my home DVD player. I am sure that if I play them with the Philips DVP642 DVD Player (I searched for this player using the tool you suggested) they will be playable.
Next Thursday I will try these DVD's in a friend's DVD player (a newer Sony model, can't recall the model number).
