Yes I have the same issue as you Darracott, I usually just exit and reconnect the Netflix app and sometimes it works after a few tries and if it doesn't, I just use my Fire Stick. As you say, every other device works 100% every time with Netflix on my network, only the 2 Tivo boxes have these issues. One hardwired, one WiFi. But my Prime also works flawlessly every time on the TiVo boxes
It seems to me that VM are sticking their head in the sand and pretending that this is not a common issue but I am more than sure it is. Netflix are saying I need to speak to VM because the app is on their box and every other Netflix app works fine in the house, which is of course a good point.
The issue is definitely with VM and I wish they would just stand up and admit it already
Very widespread, 7 people I have spoke to get the same issue but they didn't notice as they use the smart tv apps instead. Living room and bedrooms are fine as I use the tv app but the kitchen is a computer monitor connected to V6 so has this problem and I have tried everything! (new router, switch & cables!) Everything in the house is hardwired cat 6.
I have noticed that the V6 has very strange network behavior on all 3 of my boxes, they are unable to be pinged and the network card inside goes into power saving mode the minute you watch normal tv they go on and off from the network every few minutes or so.
I didn't notice the strange behaviour until I plugged them into my managed 10gig switch. It kept throwing me notifications of a port being online and offline and i thought I had cable issues, tried to ping and timed out on all 3 regardless of switch or direct. I am just assuming it's going into power saving mode but it's the only thing that can cause that behaviour especially when all 3 boxes do it. Similar behaviours are witnessed on my laptops running on battery.
Thanks for posting on the community - sorry to hear you're having issues with Netflix.
Is this on the V6 box? Do you have it connected to the Hub via a wired or wireless connection?
You can also try these tips -
Change the video resolution on the STB box by navigating to Home > Help & Settings > Video Output > Video Output Format
If 2160p (only) is enabled, also enable 2160p passthrough, then retry Netflix.
Disable both 2160p resolutions, and enable both 1080p resolutions, then retry
Disable both 1080p resolutions, and enable 1080i, then retry
Disable 1080i and enable 720p, then retry
Disable 720p and enable 576p, then retry
Disable 576p and enable 576i, then retry
Then if that's not sorted, do this;
Perform a Speedtest using the V6 Speedtest App located at -
Home > Help & Settings > Help > Our Other Products > Broadband
I have the same problem also. App on Smart tv works every time, V6 box very temperamental, have to power cycle to get it to work - such a slow process, I use app on TV. Really not very impressed with Tivo V6, daughter is on Sky and that interface does seem a lot better.
I don't know what changing the resolution will do when the issue is that the box can't connect to the Netflix server. A 25 quid fire stick connects every time without fail without changing a setting yet this "fantastic" V6 box cannot. Virgin you need to accept there's an issue with Netflix on your boxes and just fix it already
