Allow VideoStreamCopy for remote source fallback

During LiveTV playback, a fallback is usually needed because the first attempt would be try to direct play the remote url of that channel. If that failed we should still allow stream copy because the playback would still success in this case. The server side will enforce the most compatible format (h264+ts) and still do transcoding if that condition is not met.
