Shockingly poor quality stb from elsat

I have tested the elsat openview hd decoder and the Altech openviewhd stb at the same time via hd cable,via samsung led on the is20 satelite ang have found the results shocking.The elsat ovhd stb has poor picture quality(lots of digital noise)and extremely poor sound quality.The Altech model on the other hand has amazing picture quality and the sound is ten times better compared to the elsat model.I paid R1000 a year ago for the elsat model and now the altech stb is R399 and is vastly superior compared to the elsat stb.I feel as if i have been robbed.Platco needs to take full responsibility for givind elsat the green light to mass produce an inferior quality product before stringent test were conducted to insure that the elsat stb was of a high quality.Instead they sold us an inferior quality product at high cost.
