Hi Guys,

I have a problem and was wondering whether you could help me out. I have the Logitech Z-5500's connected to my PC via Optical cable, and last night, I was watching the final of the junior apprentice on BBC Iplayer HD through my Z-5500's, and the best effect it could produce was Pro Logic II, as the program was not 5.1 or DTS encoded. However, when using PL II, I notices that both the rear speakers had a swirling sound in the background, really wierd, as though there was a Darlek in the speaker or something. This doesnt happen when playing music thorugh PL II through the speakers. Any help on resolving the issue would be much appreciated.
