It was/is working, it was just missing some of the event information.
The DVB SI spec (EN 300468) states:
"The extended event descriptor provides a detailed text description of
an event, which may be used in addition to the
short event descriptor. More than one extended event descriptor can be
associated to allow information about one event
greater in length than 256 bytes to be conveyed."
The present code only extracts the text from the first descriptor. I
wondered why the program descriptions were all truncated and used the
dvbsnoop tool to look at the stream. I realized that there are often
more extended event descriptors present, which carry additional text for
My patch just makes sure that _all_ the extended event descriptors for
the prefered language are taken into account, when building the program
description, and not just the first blob of text.
