Blank DVD-R's Question

[wiespino]

Hello Guys.
I'm looking to buy some blank DVD-R's and I don't know which brand should I get to be compatible with my Sampo and Sony DVD players.
I've found so far for a good price 3 brands I never used before and I wonder if someone could give me an opinion about these brands from his experience. The brands are Leda, Ritek and Princo. Anyone using these discs could give me some information ?? Any other suggestion about another brand that works (and can be purchased in USA) will be appreciated. With the discs that I use now I'm affraid that if I buy another batch will not be the same as I understand that disc manufacturers often change the composition of the organic dye. Getting good discs these days is like a lottery...
Thanks very much !

Princo and Leadata DVD-R will not work on the lastest Sony DVD player, Ritec and Optodisc DVD-R will work... Good Luck

Thankx Babyburner, I will try Ritek. Optodisc works in the DVD Player but after the laser reads 70% from the disc, I have freezes and jumps on the disc. This happends on my Sampo DVD Player.
I don't have the latest Sony DVD Player.

What I have is:
Sony DVP S560D (2 years old)
Sampo DVE-631CF
Sampo DVE-620

Thankx
