Hi New to Freeview, on second box in 10 days (Humax now Sony) newly installed £300 earial giving good signal but sound slightly out of sync. Am I the only one? Help lines for Sony and Freeview can't really help. Anybody else experiencing or resolved this? Thanks in advance. Sharp lc32ga5E Sony VTX-D800U Profigold PGV782 scarts.
