V55 doesn't apply the transparent bridge mode here, it always reverts to the stock setting. I don't think it ever applies it.
Not sure if it's because the TV STB is plugged in directly to the V1000H at the moment, or if something else needs to be configured/unconfigured before it will accept to keep the setting? Haven't found anybody so far with similar issues with getting the bridge mode to stick...
This would be the next step to get bridge mode working for me.
Not sure if it's OK to downgrade from .55 to .48 firmware or if the result will be a brick!
