I recently made some new encodes(HLS) for roku using digital rapids. I am using the default iphone/ipad settings at the following bit rates and res.
Video: 1280x720 3500kbps 960x540 2000kbps 702x400 1200kbps 512x288 800kbps
Audio: 48khz 56kbps stereo
source is house master 29.97 1920x1080i
The new encodes come out great less the fact that the audio is slighly out of sync probably by about 5 to 10 frames when played on Roku XDS. I just got the new roku box in today and everything works great. Has anyone ran into a similar issue.
