I use the Skip Forward and Skip Back buttons all the time.
They used to go forward 30 seconds and back 10 seconds.
With a recent update they now go forward 37 seconds and back 12 seconds.
Many commercials are 30 seconds and the 30 setting worked well.
I also found that the 30 second setting worked well for parts of baseball and football games.
The industry standard for PVR manufacturers seems to be 30 seconds for Forward.
I found a Shaw Remote Control web page that said Forward was 30 seconds.
Why did Shaw change these features to 37/12 ?
