Bug: Route from progressive channel to interlaced channel doesn't play properly

[Sidonai-1]

Observed Behavior

If you configure a custom resolution 25p channel and a second 50i channel both with decklinks and route the progressive to the interlaced, the playback from the interlaced channel inserts black frames constantly.

• If you do this without a decklink on the interlaced channel it plays properly on the screen consumer.
• If both your channels are 50p, it works as expected.
