Trailer Buffer

So not sure if this unique to me or not.  Trailers have recently become unwatchable because of their need to buffer every 10-15 seconds via the ATV… I resorted to launching via the iPhone 5 and using AirPlay and it plays through just fine.  What I’ve realized is that on the iPhone I can select SD over HD - the SD stream no problem where the HD seems to be much larger and need to buffer more frequently - so I guess my question is, does anyone know if you can select SD on the ATV like you can on the iPhone?

Thanks in advance,
