Hi Sharon, it isn't that often that this
list is graced by a female presence :-)
Let's first start with what you get
currently (and wish to continue getting
with GiP 2.97+). By 'Ambulance'
I presume you're referring to
GiP 2.94 used to download by default the flashtvmodes;
we can decide what it is you get with greater certainty
if you (we) run in 2.94:
perl get_iplayer-294.pl --pid=b07xst16 -i | FindStr "modesizes"
(*Windows here, so adapt your cmd to Linux) =>
Those figures are good approximations,
so it's a safe bet you're now getting
flashvhigh uses rtmpdump to download,
hlsvhigh uses (in 2.94) FFmpeg. All 3 variants
yield the same end .MP4 file, which is
832x468p at 25FPS

The good news is that the 832x468p at 25FPS
video files are still supported in 2.97, but...
1. The Flash modes have been DEPRECATED; this doesn't
mean they do not work; if you do have rtmpdump installed
(I gather you do), they work fine with a benign forewarning
(that the maintainer plans to remove support for those
in a future release).
2. hlsvhigh mode uses a native pure perl downloader
and is lower in the "hierarchy" than the "hvf" modes.
"hls" modes had been suffering from stream corruption
when 2.95 was first released, hence the "hvf" modes
were given precedence over "hls" in 2.96+.

Have you scrolled all the way to the bottom?
will inform you that:

And there's also mention of the 832x468p at 25FPS
files I referenced previously in the table:
you linked to...

That's because the default best tvmode for 2.97 is "hvfhd"
(as explained by Shevek is 1280x720p at 50FPS)

You have several options:
There have been occasions (like Red-Button-only
Summer Olympics coverage) where the 468p files
were unavailable; in that case you can resort to the
new "hvfvhigh" tvmode, which fetches files only
slightly bigger in size (960x540p at 25FPS, i.e. still SD).
If you decide to take up Shevek's advice,
i.e. --tvmode=tv25fps, that will fetch you
HD files (1280x720p at 25FPS) whose
filesize is ca. 1GB/hr.
My discussed options will get you
SD files with sizes ~ 600-750MB/hr.
Have a nice week,
