Hello MBoozer, Thank you for contacting Cox Social Media team. I've provided answers to your questions below and a link to Contour 2 features. http://bit.ly/2zTyL4d
-Would I still have the SWAP button and feature with Contour? The swap feature is not needed on the Contour 2 (6-tuner) receiver Contour 2 allows you to record 6 shows at once and watch all your recorded shows on any TV in the house. For instance 5 shows can be recording and you can change the channel to a different channel to view while recordings are in progress.
-How are all the TV's attached to the DVR? Will I have cables to both TV's from one Contour DVR? The primary tuner connect to one TV and the additional Tvs will have a client box that you can playback the recorded shows on. Each box has separate wiring similar to your current setup.
-Can an external drive be added to Contour DVR to expand capacity? The boxes do not support external drives.
-Do I loose any other controls if I go to Contour box? OLd questions here seem to show that Contour doesn't have slow motion for recorded shows. Contour has various new features that the older version does not support. See the link above.
Let us know if you have any more questions. Thanks
