Whilst I have access to the UK, looks like stv.tv is restricting viewing to Scotland only, and hence Im blocked from viewing and thus testing.
Please provide debug logs as per https://support.jaksta.com/discussions/topics/6000009063 whilst trying to capture in auto mode.
Also try the DVR capture method - that can capture most sites.

STV Player has changed their website and nothing works now.
Can you get your software to work?
