I've had this problem for a month or so. Recordings made on my local channel 3 (CBS) sometimes are unwatchable due to the fact of constant stuttering and digital artifacts. For example, I recorded yesterdays Bears game (3.5 hours worth). Could not a watch any of it. Whats really weird is the commercials are fine, just the actual show is messed up. I have not had any other problems on any other channels. Just local CBS. Almost always the local news(at 10pm) is messed up when recorded. What's also weird is that LIVE, there are no problems. Just watching recordings of what I watched is messed up, any only on CBS, and only during non-commercials! Anyone else with this problem? Is it my receiver? Is it CBS? Is it the latest version of firmware (0x740)?
