I have Roku and the PSVue app which get my local channels. Do I still need an OTA antenna or can I just use the Plex app/DVR to record the tv shows/movies that I want to record. I know the PSVue cloud dvr holds items for 28 days but often for me that is not enough time. Thanks for any help.
PSVue is a streaming service like Hulu. Plex can do nothing with that.
you need an antenna and a supported tuner that the Plex Media Server DVR can connect to.
