Does Live TV buffer as well? If yes, as a test try running the Tablo with no HD attached. Live TV will still work. If buffering goes away could point to a hard drive or USB cable issue. … or possibly a weak Tablo power supply.
All electronics are affected by heat. Several people have used laptop coolers to keep their Tablo’s cool.
But typically buffering is usually WIFI issues. You don’t say if it is a network or HDMI Tablo or is you are using wired or wireless. What streaming device do you use, is it wired or wireless. A wired network is optimal.
My Tablos;’ are all wired as are my streaming devices. I have never had a buffering issue since 3/2014.
This could just be due to some network congestion. If you run into this again, try power cycling your router and Tablo. Keep in mind the change you’ve made to the recording quality setting will only be active for new recordings, and not existing ones.
6 years ago when my Tablo was brand new I was experiencing a similar problem especially if I was using 3 or 4 tuners at the same time. I purchased a laptop cooling pad and haven’t experienced that problem since.
I currently have 2-4 tuner Tablos with 2-5Tb Seagate USB harddrives sitting on the cooling pad and they have been running for 6 and 4 years with no major problems.
@Jim1951 I’m using Seagate Expansion 5TB drives.
I don’t believe this exact model is still available since I purchased the first drive in 2015 and the second drive in 2017. Both drives are still working fine and are approximately 75 to 80% filled. I keep a lot of recordings but try to maintain around 1TB free for new recordings.
