YouTube buffering issues

Ever since wonderful TiVo took away the download manager it has been impossible to watch anything on YouTube. Whether directly through the TiVo menu for YouTube or if I stream it through my iOS device. No issues on my devices or computer but only when going through TiVo
Any possible solutions would help.
Doing speed tests on my internet I'm getting between 50-60 download speeds and 25-30 upload

Thanks, worst thing TiVo did was disable the download manager
