How can I see these buffer overruns?

How long have it taken for them to show up previously?
So far I have recorded about 6 shows which have had subtitles and scores
that didn't with the buffer overrun prone code in there (whatever it
is). In my early tests I kept a close look at the values of buf and
outpus which from the looks of it points to the buffers. They wrap
nicely every time, but I guess that's not the problem.

In certain cases, data should be overflowing any given buffer with the
current code then? I'm probably not the best person for that job, but I
can look at it some more. I just don't think I have actually experienced
such an event.

I think the biggest string length I have seen have been 41 (0x29) and
that didn't seem to cause trouble..? All my subtitles have been fine
thus far.

Well, I'll see what happens when it's kept running for a few days...

Do you have any info on what channels people were watching when they got
a buffer overrun? Recording or Live TV?

I'm currently looking through the archives to see if I can find
anything. I see that the problem is supposed to be in
FormatTeletextSubtitles, so I'll try to understand what that does in
more detail...
