Just tried it and it works for getting the PAT and PMT from the satelite 
stream. However it crashes on streaming with the following errors:
BTW the CVS is of date 03 april 2002 (8:45 - 9:00 aproximately)

Segmentation fault

The ASSERT ERROR are exactly the same problems we encountered with 
streaming. The solution I found was getting SyncFifo thread safe and 
alter the behaviour of putting packets on the SyncFifo. The convertor 
first checks if there is room on the fifo before getting a packet. See 
the patch I submitted earlier.

I also checked the patch against this CVS version to check if it solves 
the above problem.

The conclusion is that it interferes with PAT and PMT discovery of the 
DVB input module. How exactly I do not now yet. It needs some more 
investigation to exactly pinpoint what goes wrong where. This week and 
probably next week I do not have time to
exactly do that.

What is your vision?
