如题，机顶盒型号是移动的魔百和cm201-2，系统更新后，用手机投屏出现：
New play cast remote content failed Error：The immediate transition from current to desired state not supported。State'com.cmdc.android.mtpi.protocol.dlna.cling.statemachine.MyNoMediaPresent' doesn't support signal 'stop'. (HTTP response was: 500 Internal Server Error)
在手机端出现以上错误提示，请问各位老大，此题何解？谢谢！
