zxl, many thanks. It seems indeed solved almost all of my problems with the device. Every source i tried now can be recorded and even recording quality is improved. If anything i noticed some issues with my PS3 recording, sound was captured with some noises, though after i turned off multichannel output on PS3 this problem also dissapeared. I wonder why not put this firmware in download section, is it still beta or something?
Anyway - this firmware indeed solves many issues we encountered with HD Cap X, so i recommend to try it, guys.
