I recently bought 1*25pack and 1*50pack of Memorex 4x media from Future Shop. The 25pack was good quality Ricoh JPNR01, recorded using BenQ DW822A @ 8x, media test below:
The 50pack was OK quality (or am I wrong?), media code Ritek R02, also recorded using BenQ DW822A @ 8x, media test below:
Maybe someone can comment on the results of the second media test...
