Anyone else have this problem? Both my VIP 612's skip forward functions have started behaving unpredictably. when I hit "skip forward" nothing happens, then about 10-15 seconds later, it will start skipping. If I have hit the skip 6 or eight times, then 10-15 seconds later all pushes will activate in rapid succession. Doesn't do this every time, but often enough to be quite a nuisance. Since both receivers now do this, I assume it was caused by a software update.
