My HR24-500 also locks up at the end of the Sam's Club commercial and has for a couple weeks on different channels, "local feed" and satellite. Suspect code imbedded in it is something my receiver doesn't like. The pause/unpause has no effect. Channel change or rewind unlocks but drops to live feed and the time between is lost.
The buggy Sam's commercial seems to run on a lot of channels.
No effect on the recording of a program, but it will lock when playing the recording also. I just use the jump fwd to escape the bad frame/code section at the very end of the ad.
Sam's may have embedded a pause instead of a stop or a "return to live" command.
Sam's commercials just recently started here (or I didn't notice them before - I prerecord - use playback or chasing playback and fast forward through commercials). Surely they know their ad is causing problems.
That all the details I recall.
