It's not just 63431223453538546, thats (I think) a unique hash. In my case, it ended with 666. Anyway, just find the folder, which contains xil.xml. In it, find tag <cntry>SOMETHING</cntry> and change it to your country.
For example, if you're from Spain, and you see <cntry>kr</cntry>, it won't work for you and you have to change. The best way is to see which videos you have in your XMB, find it in XMB, and then change all the <cntry>SOMETHING</cntry> to, lets say, <cntry>es</cntry>
Then you'll see all channels.
