Have a Pace DC758D with an expander that isn't recording correctly. It shows that it has recorded the full TV show for 1.01 hours. However during playback after 20 minutes or so, it will show that it only recorded 44 minutes. When it gets to the end of the 44 minutes it stops leaving me 17 minutes short of the ending. This has happened on a number of different shows. I have reset my expander and PVR a couple of times but it hasn't helped.
This doesn't happen with every show but does happen often enough to be annoying. Mr PVR is 60 % full, so it isn't a space problem.
