Burnt DVD will play on pc, not stand alone?

[jpmcnown]

I've burnt a lot of dvds, and never had this problem. I know that my DVD player can play +/-r, and rw's I have tons of previously burned dvds that work fine. The other day, I reloaded my os(xp pro) and I use dvd decrypter to burn iso's. I've used all 3 type of media that I have (khypermedia, artia, and ricoh) the problem that I'm having is that the dvd burns just fine, no errors. When I load it in my burner, it loads up windvd/wmp9 and starts playing just fine. But when I put it in my stand alone, it doesn't? I re-burned a movie that I recently burned(still on hd) with the same media, with the same software. One works(previous to reload), the other doesn't. I am completely lost. Has anyone ever had this happen to them?

What I've tried is
1. Nero
2. Roxio 7 and 6
3. DVD Decrypter
4. DVD Shrink w/nero

Everything burns fine, and plays on the pc without errors, but when I put it in the player; nothing. Please help!

Well, I re-installed everything again, and still nothing. Please tell me that someone has come across this problem before.

This would indicate that burning software and process are fine. The problem must occur earlier during authoring, re-encoding, etc. Post your whole process from the start.
