When I click on the E-Contents, a message 'Only available on IE.' appears and cannot watch the content.

Check the 'estream' setting of the content.

It is an option to select when you register a content in a format called eStream.

If it is set to 'estream - Yes', the above message appears and you can watch it only on Internet Explorer(IE).

You can change the setting to 'estream - No' if the content is not for Internet Explorer(IE) only.
