@Craig_Holliday, just had a chance to test out HEVC content on the AppleTV HD, and it looks like it is defaulting to h264 for transcoding now, even with the HEVC server preview! Thank you!
However, some HEVC content is still trying to direct play on the client if it is 1080p or less in resolution. Is it possible to force an h264 transcode for all HEVC content on these older devices?
