I just tried v29.  Fast Forward and skip is working.  Either your small 
fix did the job, or...
When I tried the previous version, I was running the latest CVS on both 
backend and frontend, but I only applied *your* patch to the backend.  
Would that cause a problem?
For v29, I applied it to both the front and backend.

Ditto.

I assumed it was a frontend problem.  I tried to look through the CVS 
commits, to see if I could spot a change that would cause it, but after 
reverting all the likely candidates, the problem was still there.

Yup, it is fixed.

With the latest CVS/v29, changing channels in LiveTV, causes the 
frontend to segfault just about every time.  I watch LiveTV soo rarely, 
that I don't really care about this.  Just discovered it because I was 
testing your patch.  I have not tried the latest CVS without v29 
applied, so I don't know what the cause is.  If it is still happening on 
Saturday, I will try to get a backtrace.
