I read on here that there is a firmware for the lip synch error on the hs2 available from pannasonic, so I have contacted them, and they have emailed back, to arrange for an engineer to call with the disc. Before I proceed, has anyone had this upgrade? The reason for asking is my machine is m/region, so I need to know if that will be changed by the upgrade. Also, does it improve the flash on rgb inputs Does it have any affect on existing functions, ie worse playback or recording etc! Interested in any views. Ali.
