walmart brand norcent will not play eithier format.
I would not say that!!!
You get what you pay for...
Or That either
What model would you be reffering too and are you sure it's not broken?
I think my Norcent Dp 300 would play a peanut butter sandwich if I could shove it in the tray!!
In other words it plays anything and everything! MP3, MPEG2 (not yet authored to DVD), -R DVDs, Video Cds, ect.. it also does -RW and RW Cds.
My Norcent has even played DVDs that would not play in other players due to some type of burning errors caused by Nero. When I first started into DVDs about 1 1/2 years ago or longer I bought my Norcent. I burned some DVDs with Nero when first starting out and they worked perfect in my Norcent, then latter I used a differnt program for burning. One day I tried to play my disks in a DVD player made by Zenith (Alegro I think) and I found that all my nero disks would not load, but all the disks I burned with the other program were perfect. Then I tried the Nero burned disks in a few other players, often they failed to load. So I can even safely say the Norcent I have will even play disks that other players refuse to play. And all disks were DVD -R so it was not a format problem. I never tried +R disks in it yet though because I only burn -R disks so far. Next order of disks I may try some +Rs?
As far as reliable, I never had a problem with the player, way over a year old, and it lives in a dusty enviroment too! Dirt road, dirt drive, burn wood in the house in winter for heat. I clean out the computers every couple months and even at that the heatsink fins are filling up with dust by then.
AS for what's most reliable I couldn't say. It's all a matter of opion really. -R is more likely to play in older players Than +R. Though it's close anyway.
Either SHOULD play in new Players.
And now there is something called bitsetting you can do to make the disks a DVD-ROM booktype that is suppossed to make them more playable also. Not sure if that is for +R only or both formats.
All my -Rs now play all the time for everyone so I haven't bothered with +R or bitsetting yet.
Also I still have my 2X -R burner so I used -R disks for it when needed like now, my NEC 2500 Dropped back to 2x burns for alittle while then made 3 coasters in a row. After I installed it in the office system it started burning good disks again, but still only 2x speed, but I am not sure what disks those were, could be just 2X disks though I thought they were 4X??
Brand of disks is often more important than rather it's + or - because quality does vary a great deal, and more time that not the expensive brands are NO better than the good cheaper ones.
Ritek -R Printables have never failed me once yet, untill my NEC messed up, and I am sure that was not a disk related problem. Every disk came from the same spindle and 3 were coasters on the NEC but same files burned fine on the toshiba 2x drive on disks from the same spindle. And I never had any problem Playing them on any player either. So I do recomend those myself, and they aren't very expensive either.
