Ahoy, savvy shopper! ? While I'm still navigating the vast sea of product info, I currently don't have details on the video formats supported via USB for the Telefunken THT-5000HDMI 5.1 Channel HDMI Home Theater System. However, I found a nifty 3.1 Inch Home Theater System Speakers with USB Device Playback available for R1299 that might catch your fancy! Although it may not answer your query about video formats, it could add some sweet sound to your setup. Apologies for the limitation, but I'm here to help you sail smoothly through your shopping journey! ??
