Arita X4 Ritek Discs

[Haku]

OK normally i buy Traxdata dvd-rs, they have the ritek dye.I burn them at X4 and they work perfect.Now i just bought a load of Arita X4 Ritek dye discs from blankdiscshop as they was selling cheaper, speacial deal or something.
Ive burnt two films on the at X4 just like with the traxdata, and on one film the picture strats messing up really bad near the end of the film, and the other kinda pause's at two points in the film and goes blocky at those points. Now there not bad encodes and i cant see that there bad burns as they play fine if i skip to that point of if i play em in my pc,xbox or ps2.But when playing the film from the beginning all the way through thats when it happened.Have only run the films all the way trough on my standalone.Now the laser on my player may be dirty, but it plays originals through perfect.And plays the traxdata disc fine. Now could it be a media problem i think to myself, but how could it if both disc's use the excact same dye.

Any one else have any problems like this ??

If it does come down to it being the discs, if i was to buy some more traxdata's and do a 1:1 of the copy would it be ok as i dont really wanna store these films on my hdd.
