DVB: Fix accidentally removed line in
594935d8d533cb30d7cfcc7d186dee50a54c4af1 "Split PM_CAPTURE mode into
PM_ANALOG_CAPTURE and PM_DIGITAL_CAPTURE"

This might cause DVB mode to lock in certain cases.

Fixes #4178
EVR-CP: Fix a jump few frames ahead when pausing the video after seeking.

The issue was introduced in 5b803b86b2b7fe138f76e65712664e466870ce97.

A forced repaint was sometimes triggered because of a flush but the renderer was unpaused before the redraw happened and it was delayed until next time the renderer was paused.

This commit fixes #4182.
CVobSubImage: Initialize all member variables in the constructor.

The variable was never accessed before being initialized but better be safe.
