Feel free to say that this has already been brought up but after watching tv this weekend and reproducing the issue, DLB's should be doable. Is this new with this version of software or has this always been around. Take channel 1 and channel 2, neither recording. If I use previous channel the buffers are lost (duhh). The work around has already been to record both. 10:50 Now I am watching channel 1 for ten minutes and I switch back to channel 2 11:00 channel 1 starts recording (while watching channel 2) 11:10 I switch back to channel 1 and rewind... I can rewind into the buffer past 11:00.... even after watching channel 2. This proves that the buffer exists on channel 1even while on the channel 2. I go to the guide (while watching channel 1) at 11:15 and record channel 2. The buffer is recorded from 10:50..... This proves that there are DLB, and the buffer is lost when changing BACK to the channel not away from the channel. DTV fix the crappy software and give me true DLB's!!!
