Dark Shadows

Hi guys I'm watching DS via the chromecast app but the problem is it won't display they show in it's proper 4:3 aspect ratio but instead stretches to 16:9 distorting the picture. When I'm watching the Chromecast I can't manually change the aspect ratio via my TV. Is there anything I can do??? The DS app works great on my PC and Roku in the bedroom, but not while casting to my big TV with the chromecast. Any help or settings I'm missing???

Thanks,
Gregg

I have finished watching episode 250 with the expectation that 251 would be next. I have paid for the entire series to watch for a year at least and I was in hopes that more episodes would follow. What is wrong? PK>
