Time to go to the top. Send an email to Tim. Example of what I sent.
Dear Mr Cook,
I hope this email finds you well.
I have a 1st generation Apple TV. Most recently iTunes movies with location subtitles (for example) have been sticking, i.e., they don't disappear after a short period of time as they should, resulting in a diminished viewing experience.
This issue is well documented in an Apple Support thread at https://discussions.apple.com/thread/4400114?start=75&tstart=0
While I acknowledge progress and technological change, and have upgraded Apple technologies on many occasion, while handing down older products for continued use, it does not make sense for 1st gen. Apple TV users to throw away a working piece of equipment because of the persistent subtitles issue. Apple upgrades generally do not make older equipment obsolete, they can continue to be used. However in this case, iTunes is making 1st gen. Apple TVs obsolete for what seems like a very silly and minor reason.
Surely there is a solution available that will help keep 1st gen. Apple TVs out of the garbage pit, and satisfy the needs of what I believe are mostly genuinely happy Apple consumers.
Kind regards,
Garry
