Hello. I was wondering if there was a way to increase performance of my Tivo Roamio. There sometimes seem to be rare instances where the video is slowed down(perhaps Tivo was overworked when recording was done?) , the tivo seem sluggish, etc.. I have 6 tuners often fully used, house full of the Mini, it has a 8TB 5900RPM seagate drive. Are there any upgrades that might help? Perhaps a way to expand RAM? Maybe a hard drive with 7200 RPM, 10,000 RPM, 15,000 RPM, etc...? are there defrag options or other hard drive tools on the Tivo that might help?
