Would it be possible to insert a segment from some other video into the data stream by spoofing the desired data? Granted, I don't think it's happened so far, but then that's not to say it won't given the right motivation. I don't see connecting to church servers for information from where to download as providing protection from that.
Also a MD5 hash of the segments would be hard to spoof due to a few mathematical laws surrounding hashing. Anyway the church servers could provide the list and the hashs to the client and if the client got a bad segment it would then select another server to download from.
