Hey there @puneetmathur, unfortunately there's no way of getting the YouTube app back on the current Fetch unit that you have.
As it's now only available on the Mighty unit, if you require the YouTube you will need to update your STB. This wasn't a decision made by Optus and was a global decision made by YouTube themselves.
Please feel free to chat with us HERE if you'd like to upgrade your unit and we can organise it for you.
So heres the next question.
Once I upgrade to Mighty what happens with the old Gen 2 box. Can it be used as a multiroom box, or do we just bin it??
Next question what happens to recorded content on Gen2 box can it be transfered to Mighty. This part is insane as Ive had a box fail before and you cant get your recorded content off the box. Can the Mighty record to an external drive so that if something goes wrong you still have the recorded content. This is more of what a Media Hub should look like rather than recorded content lost with box.
You can potentially use your Gen 2 Fetch box for Yes TV by Fetch Multiroom.
In order to share content, note the following:
All boxes must be on the same Fetch TV account (up to three set top boxes are allowed per account)
Multiroom works on Mighty, Mini and Gen 2 Fetch TV boxes connected to the same local network (either via Ethernet or WiFi) and attached to the same account
We'd need to process the order in such a way as to not deactivate your current Fetch set top box. That'd be us simply attaching a new Fetch box to the account without cancelling the old one.
There's an additional $15.00 fee to access Multiroom, You'd probably be better off organising two Fetch Mighty boxes or even a mini for an extra $10.00 per month. What ever you do, do not dispose of the Gen 2 set top box. If it's not returned to us, you'll incur a $199.00 non-return fee.
You should be able to use a USB external hard drive to upload any recorded content on the device. Have you given this a shot?
