Hi, been using my new Tablo for a couple weeks, and am trying to troubleshoot this problem. My main problem is that playback is unwatcheable due to buffering, and yet LIVE TV through Tablo is perfect. So before I just start buying a lot of new gear I’d like to narrow it down to the root cause. My system is detailed at the end.
-Live TV thru tablo on TV (with chromecast), no buffering at all.
-Live TV thru Tablo to Android phone, same… no buffering.
-Playback, streaming to android phone, it’s ok most of the time… but I occasionally see momentary digital breakup. Not a big deal, I guess… but I don’t see that at all when watching Live, or when watching live direct from antenna to TV.
-PLAYBACK, casting from phone to chromecast on TV (or even to laptop) I get constant buffering. It’s unwatchable… buffers for 15 secs, plays for 5, buffers again, etc. And HERE’S THE KEY POINT… it seems to occur only when there’s any kind of signal variation from the TV station transmitter. (I’ve tested live TV direct from antenna signal strength, and those signal variations coincide exactly with the buffering issues.)
I’m starting to think that it may be related to how Tablo handles signal strength variation coming from the antenna. Yet it’s a good tuner and a great preamp. Or maybe the hard drive. Or the Chromecast (I’ve read all the issues on that, but if that’s the problem, I don’t understand why Live is good and playback sucks). More info…
When watching playback from a live channel (direct to TV, no Tablo in-line), there are occasional reductions from “full strength” (10 bars on signal meter) to about 7 bars, maybe sometimes 4 or 5 bars. These are quick, lasting about half a second or less. Since I’m not right near the transmitter, that’s to be expected. My TV handles that fine, as it’s designed to do… I never see it. Tablo handles that fine on Live TV. So why only on playback? If you have to have a constant 100% signal for Tablo to work, then I need to send it back pronto… I’ll never get that where I live.
I’ve read here that Chromecast can be a problem, and I need to get another streaming device anyway so I’m thinking about getting Roku 4, hardwired. Or maybe Nexus Play. But I’m not sure if that will solve the problem, since Live streaming is fine.
I could buy a different hard drive. But I formatted it in Tablo, it’s a good drive, had very little use until now, no disk errors, etc.
I appreciate any help. This cutting of the cord is getting a little expensive! But of course it will be worth it in the long run.
PS I have over 35 years as a professional TV director/producer so you could say I’m pretty technically competent, and I’ve tried all the obvious things.
Tablo hardwired to router (tried different ethernet cables, no change)
Chromecast (version 1)… about 4’ from Wifi router, solid 5bar/100% signal measured on android app
Netlink WRG614 v9 It’s wifi G
Android Moto X phone running lollipop
Hard drive: 500GB WD 3200H1U
Winegard HD7084P Antenna with Channelmaster 7777 preamp
Digital 1x2 splitter (splits signal to TV and Tablo. I tried with no splitter, just tablo, no change)
I have no other 2.4Ghz traffic, no kids in the house anymore, microwave off, no 2.4 phone, etc. So a new router doesn’t seem like the first solution.
