For the past two weeks, the sound starts skipping when we fast forward or rewind either live or recorded shows. Sometimes, it can be fixed by fast forwarding/rewinding another couple of time... sometimes not. When starting a new recording, it even cuts the sound out sometimes. It seems to be getting worse and it is definitely annoying! It started after the PVR froze during start-up and we had to reboot it (which happened again last night). The box is connected to a splitter (cable modem as well) and we have an hdmi cable connecting it to the tv. The box is a Motorola DCX3400-M.
