Does the 'Last Channel' button work for both Tuners? I mean, if for example, if you are on Tuner 1 and to go channel 10 and then 20, then when you press the Last/Enter button, it just jumps between these two channels. Then if you press the Swap/Tivo Live button and swap to Tuner #2, and say it is on channel 100. Then you change to channel 200. Now shouldn't the Last/Enter button jump between channels 100 and 200? And if you change back to Tuner #1, the Last/Enter button should not jump between channels 10 and 20. So, each Tuner has it's 'own' Last channel in memory?? I swear it was working this way for a while, but it has stopped. The manual says nothing about this..
