I have been watching two tv shows on two different networks, and going back and forth. Then I tried to back up one to see what I missed, only to discover that the dvr won't allow me to back up? Is this normal operation for a Cox router? I have been with two other cable providers, and their dvr has never had an issue backing up, unless a show is being recorded.
I'm not sure it's that, but on my old Verizon Fios DVR, I could simply change a channel to something else, then go back and rewind the original channel, then switch back to the 2nd channel and rewind that. This is basic DVR service... even the really old one from DirecTV had that capability. The tech described what the Cox dvr does as "buffering the current channel" but once you change the channel you lose the buffer.
And if the Rovi platform has the capability, why is it not enabled???
