Hi,
I just tested vdr 1.3.41 and found that switching the channel with up/down doesn't works anymore.
Hitting up/down brings up the channel info for the current channel only. I can hit the key as many times as I want, nothing more happens.
I can switch to the channel if I enter the number directly and the up/down keys work fine e.g. in menu.
I'm using a LIRC remote. Tested with plain vdr/no plugins too.
Regards.
