My Bolt for Antenna exhibits the following: sometimes when watching a recording and you come to a commercial, pressing the 30 sec skip 4 times will instead of skipping two minutes, skip to the end of the show. Doesn't seem to matter how many 30 sec skips I press. It does the same on the 7 sec skip back button too, skips back to the beginning.
Also the TIVO status progress bar at the bottom of the screen will not auto disappear unless I press "Clear" on my remote, ( I changed to fresh batteries too). However it does resume shows correctly so its not quite the same symptoms as yours.
