VOD stream rejecting RTSP request with "457 Invalid Range"

[ParkerKemp]

I'm streaming some videos from my computer to my Android device. Some videos stream just fine, but some will not play because the PLAY request is being rejected by VLC for inexplicable reasons. Here is the conversation between the client and server:

As you can see, VLC is complaining about an invalid range in the PLAY request; however, the range appears to be valid, since it's exactly the range specified in the SDP file. Is this a bug, or am I just overlooking something due to inexperience?
