The 6000 does this very well. I recieve all the analog and digital stations over the air via the 6000 (and I assume it works the same on the 811). You just change channels to 006 to go to channel 6 OTA. It defaults to the digital feed, if you want to go to analog you would enter 00600, or a specific digital feed like 6-2 you would 00602 and it pops right there.
The 6000 also does CATV.
