Black Screen on CS's

[Strify]

I play on PS2 and several cutscene's I've been after lately don't work. They start to play, and then my screen just goes black and nothing happens. My ps2 however remains on. (I don't have any alternative systems to view these CS's on so please don't suggest that.)
I've searched similar situations on the web. and others who have reported black screens have had them fixed by SE by splitting the CS's into smaller parts. I'd really like this done as these are crucial cutscenes to the game's storyline and this problem shouldn't be over looked imo. The following CS's black out for me:

• Windurst Mission 7-1 The Sixth Ministry, NPC Tosuka-Porika at the Optistery in Northern Windurst Waters (G-8)
• A Crystalline Prophecy Mission 2, ??? at (G-6) in Qufim Island

Btw, does anyone else have this problem with these certain CS's? Please fix this SE.
