When I watch DVR'd shows on my non-DVR box, the 30 second skip stops working in the middle of shows. This does not happen on the DVR box itself. Verizon has already sent a replacement box and same problem. When it happens, the display looks like there is no time left in the recording. When I hit stop and the resume play, it jumps about 10 minutes back in the show but shows the correct time remaining. It is particularly annoying when watch longer shows because I have to stop and go back in several times. Clearly replacing the hardware didn't fix it. It seems to me to be a software issue. Am I alone or is this a common issue? Thanks.
