Over the last few weeks I've had a problem with recordings. When I play them back there is video and audio freezing going on-the same when I ff. Live tv is fine. If I pause and buffer a program the same problem occurs. I've tried a soft reset, pulling the power plug, etc. System and network test show ok...I've got 30 hours of programs to watch and hate to replace the box and lose them....Any suggestions regarding this problem, or any way to offload the current recordings?
