Pro Tips for Buffer-Free Playback on Firestick

• Enable Hardware Decoding: Within your IPTV player's settings, change the Video Decoder to Hardware (HW+) to leverage your Firestick's GPU.
• Adjust Buffer Size: Set the buffer cache to Medium or Large (3-5s) to mitigate issues caused by Wi-Fi packet loss.
• Clear Cache Weekly: Navigate to Settings > Applications > Manage Installed Applications > Clear Cache to maintain optimal Firestick memory performance.
