Crunchyroll app video stuttering on some shows.
I was watching the english sub versions of Star Blazers Battleship Yamato, Murder Princess, Sacred Backsmith, Buddy Complex, and A Certain Magical Index The Miracle of Endymion on the Roku App and noticed the videos would stop briefly while still playing audio. I would notice the picture was not moving for a few seconds it was very jarring.
I tried reseting my Roku Ultra, clearing the cache and reinstalling the app. I've also tried rebooting my modem router combo from Comcast. It's a XFi XB8. I tried wireless 5ghz and ethernet with no difference in playback. I tried on Roku Premiere and Roku Ultra LT with the same issues being present.
I think the issue may be my home network because I hooked my mobile hotspot to the Roku Ultra and the videos played smoothly compared to connecting to the modem/router combo. Other shows like Jujitsu Kaisen, Rurouni Kenshin, Kingdoms of Ruin, Burst Angel, and Angel Beats play smoothly. I have not had issues playing videos on the xbox series X, google chromecast or mobile phone. I love using my Roku Ultra though.
I got on my kids roku onn tv and played the same crunchyroll videos and didn't have any stutter issues. I don't know if its a network issue or a Roku Software issue at this point.
