Using the usual "01-BBC1.London.News.ts" and comparing with playback via VLC (which is perfect) I can see that out timing is off and we have a number of issues.

First, in .srt
1
00:00:00,001 --> 00:00:00,000
Where am I? Where am I?!
Where am I?!

The first problem is obvious, with the end time being before the start time for that time.

In spupng that line looks like this:

The other thing is that the "Where am I..." text appears in VLC (in sync with audio, so they have it right) at around 00:04:xx. It doesn't appear immediately as both our .srt and .xml do.

Moving forward, picking a random line:
"Is this all a joke to you?"

Appears in VLC at 08:48, but we have it at
00:08:40,307 --> 00:08:42,976
Is this all a joke to you?

The final subtitles in VLC are
Jane had squeezed my hand.
Yeah. . .was it just that?

which appear at 16:57. We have this at the end:

334
00:16:49,197 --> 00:16:51,966
Jane had squeezed my hand.
Yeah. . .was it just that?

335
00:16:51,967 --> 00:16:55,346
Or was it to do
with the sentencing as well?

The final frame (335) doesn't appear with VLC at all, and that's correct as the audio isn't there.
