When you typed "ITVX" into your topic title, did you not get numerous suggestions of threads that had already been posted and check any of them? If so, you would have realised that ITVX is not available on the older TalkTalk YouView boxes and ITV Hub was discontinued in November last year.
From the 29th of March our TalkTalk Community will move to peer-to-peer support and the TalkTalk team will no longer be here to support with queries. Don’t worry we still have plenty of ways to reach out if you need to speak to TalkTalk directly. For more details check out the link here:
