Yes...

Skip to Tick Forward: Hold the FF button for 3 seconds
Skip to Tick Reverse: Hold the RW button for 3 seconds

Note it isn't a 15 minute "jump" (neither was the TiVo)
There are pre-placed tick marks at 15/30 minute intervals (depending on how long the recording is)

Can someone explain what happens on the DirecTV remote when you hold FF for 3 seconds? Does it put a gap in time after 3 seconds before it sends another FF command which the HR20 understands as a command to skip to tick? Or does the DirecTV remote send out a different IR command all together if FF key is held for more than 3 seconds?

If so, it would be cool if we could train our universal remotes that different IR command so that we don't have to send FF for 3 seconds (seems like a waste to me...)

thanks!

From what I have been told it is a different IR signal sent.
But until I get the IR code dump from DirecTV... I won't know for certain.

My skip to tick works basically as described. But I've noticed that it will not skip to the beginning or end of the recording. It's almost as if, lacking a tick mark at that point, it doesn't see anything to skip to. Is this right or am I doing something wrong? Perhaps it's a bug with my machine - I don't know.

No, that is correct.

You can use:

Hold Forward Advance (30s) for 3seconds to jump to end
Hold Reverse Jump (Top Left from Play) for 3 seconds to jump to the beginning.
