Recordings do not start where left off on app

we have one DTV Gemini receiver and use the DTV app on two other TVs (one FireTV and one Google TV)....when accessing recordings on the two TVs that use the app, the recordings do not start where we left off, they all start at the beginning. (The recordings work fine on the TV with the receiver)

I have:

- restarted all TVs, devices and the receiver

- cleared cache etc on apps

- deleted and reinstalled DTV apps

- checked TV s/w (all up to date)

- chatted with DTV AI and live person ; no resolution

problem started when we switched from recievers to app

any advice / help would be greatly appreciated

thx!!
