OK. This seems to cover it

The section on "Service Information" contains info on the various 'helper'
data that are broadcast within the transport stream for any particular
programme

that analogue only ?

I don't know the answer to your question because I don't know what CRID
is.

Is that supposed to be some standard, who is using it? Except for a
mention
as a draft in RFC 4078, my google finger is failing me.

As far as I know, most people dvr's here in the states use the guide and
rely on the data provided to it. So if Fox says American Idol is going to
run from 8pm to 9:04pm, if the guide is programmed to show that, the dvr
will record it. If it's an accidental overrun, no, the end of the program
will get cut off.

I noticed some dvr's like from Comcast seem to keep track of shows that
usually overrun, when you try to record it, a new screen pops up saying
it
may do so and gives you an option to record past the shown end time in
minutes.

Except for some low powered stations, there are no analog broadcasts here
anymore. I know they used to bury some neat **** hidden in the signal
back
then, but these days, no clue.

I believe it stands for C-ontent R-eference I-ndicator D-ata and is
inserted by the broadcaster to tell devices such as PVRs what exactly is
showing at the moment. As far as I know, it, or some variation of it, is
in pretty widespread use at least across Europe, and possibly in other
parts of the world. Australia comes to mind. Maybe one of our Aussie chums
might know that ? The fact that you do not appear to use it your side of
the pond, helps answer the question that I was ultimately looking to
resolve.

A few months back, I changed my pay TV service from the major European
satellite provider - whom I had been with from the very early days - to my
cable broadband supplier, in order to take advantage of a three-way
package to include my landline phone service as well, and save a cartload
of money over what it was costing me for three providers.

The set top box / recorder that was supplied by the cable company, is a
digital TiVo box, which of course has its origins in the U.S. Over the
few months that I have had the box, I have grown to hate its shortcomings
and little foibles, and long to have my satellite box back. One of its
biggest problems is that if a programme such as a football match or the
news over-runs for any reason, and the box is set to record the programme
that followed the one that over-ran, it does, as you say, just go ahead
and record anyway, and miss the start - or possibly even the whole - of
the wanted programme. You have to have 'padding' minutes set either side
of a programme to accommodate slight late or early starts, which often
leads to stuff that's already recording getting truncated.

The satellite box never recorded at the wrong time, because it can read
and action the CRID. My cheap supermarket Freeview ( UK terrestrial
digital TV service) box can also read this data, and likewise records the
programmes correctly. Now I know that this data is not common in the U.S.
, I guess that explains why the TiVo box doesn't action the data. I don't
suppose it knows how ... :-(
