The Sony 710 doesn't seem to pass on the WSS (wide screen selection signal) when running progressive over component cables. This means that the 4:3 signals are fat and have to manually select sizing using TV remote. Help! it's really frustrating .. and I'm resorting to watching in interlaced to avoid the hassle - when it works wonderfully. Update: this problem occurs all the time, even when just watching TV using the freeview receiver of the 710. There is another separate issue with recording the discs, but this problem with WSS is just playing live signals.
