I have experienced the audio stutter while watching live TV and had hoped 9.3 would fix the problem. It didn't. So when my video just starting freezing up one night I decided to call TIVO. What was strange was that the Video would freeze but I could see it all via fast forward so I know it was recording. What I was told by TIVO was that the stutter audio and video can be caused by a bad network connector (I use TIVO wireless adapter) or a bad cable card. So today I rebooted without the network adapter connected and so far so good. But a reboot always fixed things for a while. Has anyone else been given this weird advice by TIVO?
