An OSD device was added to the new API only recently. You have
to upgrade to kernel >= 2.4.1 and get a current driver from CVS.
(or use the old API, but I don't recommend this)

PAT and PMT are in ISO 13181-1 (Part 1 of the MPEG-2 standard),
which is _not_ available for free.
The others are in ETSI EN 200 468 "Specification for Service
Information (SI) in DVB systems", which is downloadable from
http://www.etsi.org/
Additional informtion can be found in ETSI ETR 211 "Guidelines on
implementation and usage of Service Information (SI)".
