there are equivalent pages in the v2 DNAS to the v1 DNAS for seeing that information.
however, the identifier of the v2 DNAS you've posted is from one using one of the beta builds and those don't work in the same way as you often need to explicitly add /index.html or /index.html?sid=# (where # is the stream number) to get to the stream summary page.
really no one should be using such an older build of the v2 DNAS so if you know who it is or if it is one of yours then you really need to be using the public build.
When I look at the .pls files for every stream they are all the same, only the quality number changes (32/128/192/256/320) so if I remove that number and add index.html it always takes me to the same url..
that's why the ?sid=# part is needed to target a specific stream if multiple streams are hosted on the same v2 DNAS or going via the 'stream #' link which is shown on the base /index.html page. though i'm not getting why it seems like you're trying to get the information of other people's streams (based on how things have been worded).
