Playback of CBC Network recordings works fine at 1x speed. Fast forwarding at 2x also works, but when increasing to 3x or higher it spasmodically jumps forward and/or crashes.  Rewinding crashes the recording every time, wherein the playback is closed and an error message pops up asking if I want to record the next occurrence of the program. This has been going on for 2 weeks now and only affects recordings on CBC Network. Is there a solution to this problem?
