If the stream is not smooth and has playback problems, check these:
- Streaming-app: Use the recommended app dream Player
- Internal network: Depening on your wifi. Check if your wifi signal strength is good. Also make sure not to use 5 GHz wifi
- External network: Streaming over a cellular connection (e.g. UMTS) might be to slow for HD streams. If your receiver supports transcoding, try using transcoding for the external profile.
