Yamada and Maplins Tangent - photos reproduction "banding"

[asherpat]

Does anybody know which chipset is on the Yamada DVD player (also the older Maplin’s “Tangent” DVD machine)? The reason I am asking is that this chipset seems to be very popular in el-cheapos DVD players but the reproduction of JPEGs on these DVDs is bad - there is strong "banding".

Anybody also encountered this problem?
