Hi, Been using my Zidoo X10 on the fw 1.4.12 as a secondary player only attached to my tv. Today I just bought a 4K beamer from JVC and moved the player to the projection room. Wanted to test some 4K movies that are on my server. Picture quality is perfect but sound is awful... sometimes I get harsch cracks or skips in the sound and when it does work no bass comes out of the sub. Any1 got any ideas? I use a Arcam AVR850 also on the latest firmware. Thanks!
