We've been having the same issues for a couple of weeks now too - both Netflix and Amazon Prime through the TV are intermittently playing up. I can usually start a programme and then only a few minutes in it all crashes saying there is 'something wrong' or 'a problem trying to show the title'. Sometimes the apps don't want to load or take a long time.
This issue is only when we try to watch on our TV, there is no issue on ipads or anything. Restarting the apps don't always work. It is not a problem with the internet connection as that has all been tested and all other devices still work fine.
This is getting really frustrating now to not be able to watch properly on our TV. And the fact it is happening on both Netflix and Amazon Prime, and only on our TV not on other devices means it's a Virgin Media issue (and as I can tell from the other posts about this, it is a common issue).
How can I get in touch with someone to fix the problem?
