Looks like it is finally starting to happen. Lost Remote is reporting that one of their users was unable to timeshift (forward, etc.) during a HD broadcast of American Idol (using a Comcast HD-DVR). Other people have reported that they had similar problems as well during several episodes of 24. The screenshots seem to indicate that this is 'by design' and not a bug.

It's only a matter of time before all Cable companies will tell us what we can or can't do with our equipment, so enjoy timeshifting while it lasts.
