I wonder if anybody has the same problem :
I bought some Sentinel DVD-R 4X disks and I have big problems playing them on almost any system I tried ( including PC/Home Cinema/Xbox/Universal Player and so on... )
It seems that if they get hot ( after about 50 min or so ) they just stop playing , the various messages from various hardware is disk dirty/not supported disk freezes in Win DVD and other errors.
I recorded them using 4x and 2x speeds with the same results.

Any suggestions on what disks to buy and if there is a way out of this situation
( I have about 50 of them left )

I use them with Toshiba SD-R5112 DVD burner and they are perfect when replayed on PANASONIC DVD S35 player.

I am burning with Nero 6 latest & ASUS DVD-RW-0420P
... to be totally honest the one and only devide that played them without any problems was a DVD/DivX player (KiSS or something like that I think ) but they will not play on my Sony DVD

There's a pretty decent DVD Media list here.

jtclipper:

So far I have tried only those 4 DVD-R brands: Sentinel 4x, Traxdata 4x, Emtec 1-4x and Princo 1-4x. All 4 play without problems in the Panasonic DVD S35; there is complete menu (language and subtitles), chapter seeking and extras on these burned DVD-Rs...

AFAIK, sony has shitty support for burned disks in players that are older than about 6 months.

I can confirm this I gave a few disks to Sony DVD owners ( 4 of them ) and they all have prolems, maybe is because Sony has money coming from copyrights and things like that

I have a Sony DVD player that's almost 2 years old, and I have played about 15 or so DVD+R discs in it so far without any trouble. Maybe it has something to do with Sony's investment in the +R consortium?

player: Sony DSP-NS500v DVD/SACD player
burner: Lite-on LDW-401s
media: Memorex, TDK (how do you check media brand on DVDr?)
they also play fine on my 2 year old playstation 2

Well I found those
Great software DVDinfo

I plan to investigate more but I believe +R is the way to go so I might have to buy the plextor writer

Could also have something to do with your player being SACD.

...just want to dig up this thread to post an interesting fact.

I used to stick labels on my DVD's and they seem to cause problems with balancing and heat on some players. I noticed that yesterday when I stick some labels on a few old DVD's I had lying around and ...*boom* problems during the end of the disks all the time.

just though that people should know.

Yes, very common mistake to use labeling stickers on DVD. Paper, glue and the Polycarbonate of the disc all have a different coefficient of expansion. When you put them into the DVD player/drive, they warm up and expand differently, leading to tension and mechanical warpage. The laser can't follow the tracks anymore and gets defocalized. This phenomenon is much more severe on DVDs than on CDs, because of the smaller track width.
