Sudden Jump

I have had 2 instances of this happen now. I wrote the first one off as just a glitch, but now it has happened twice.

At approximately 1hr 23 min into Robinson Crusoe at the start of a commercial break I hit the 30 second skip one time and had an immediate end of show delete sign in the bottom right hand corner as if the show had ended. I selected no and went back to the list and hit play again as resume was not an option. The show started over. I fast forwarded to the 1:23 mark again and did a 30 skip thru the commercials which now worked. I skipped thru all of the commercials in the break and resumed watching the show, with no further difficulties. I have NOT activated skiptotick. I can't tell you what the other show was that this happened on, just that this is the second occurence.
