 If you're using IPTV middleware like **m3u-editor**, **dispatcharr**, **Threadfin**, or **xTeVe** to manage your streams, you may need to adjust nodecast-tv settings for optimal playback. These tools typically use passthrough mode, which preserves original codecs (like HEVC/Dolby) that most browsers cannot decode natively, and may also trigger CORS restrictions.
 
+**Output Format Compatibility:**
+
+| Middleware Output | Works? | Notes |
+|-------------------|--------|-------|
+| **HLS (`.m3u8`)** | ✅ Yes | Best option. NodeCast plays HLS natively. |
+| **Raw TS (`.ts`)** | ⚠️ Maybe | Enable **"Force Remux"**. May fail if middleware proxies the stream. |
+| **Proxied TS** | ❌ No | If middleware proxies/rewrites the stream, NodeCast's FFmpeg can't read it. Use HLS output instead. |
+
+> **Why Proxied TS Fails:** When middleware is set to "Proxy" mode, it wraps the stream in its own layer. NodeCast's Remux/FFmpeg can't parse this format (error: `Invalid data found when processing input`). Configure your middleware to output **HLS (m3u8)** instead.
