So my HTPC setup is pretty solid. But I have issues when I try to view movies on my iphone or ipad. I use MakeMKV to rip and Handbrake to compress and convert to mp4. I'm using a wireless drive to store the movies and can access them on my ipad or iphone. Some of the videos work flawlessly. I'm using the seagate drive and app for the programs. Others work, but with no sound. Any ideas? They all work fine on my HTPC.
