Yes, what DBCC OPENTRAN tells is that there is no uncommitted transaction 
in the transaction log.

Or, in another words, DBCC OPENTRAN tells you that there no uncommitted 
updates. But there might still be open transactions that hitherto only has 
performed read operations (but which might hold locks, depending on the
isolation level.)

1 and 2.

The process is not running. It could be because it is awating a command 
from the client, but it could also be waiting on I/O completion or a
locked resource to become available.
