It's unusual to see systematic packet loss (independent of the receiver(s)) occurring with LIVE555-based *servers*, unless the output stream is exceeding the capacity of your network. But because "bipbop-gear1-all.ts" is such a low-bitrate stream, it's unlikely that network capacity is the problem here.
