"My LG Blu-ray player won't play MKV videos from USB!"
Hi, I bought a brand new LG Blu-ray player last week. Last night I watched a bundled movie on my 4K LG OLED TV, and the picture quality was stunning. Today, I put some MKV files onto a USB drive — they're mixed with DTS audio tracks. For some reason, when I navigate to the "Movie" section with the remote, the player sees nothing at all. I've already updated the firmware to the latest version, but that didn't fix the issue. Any help would be appreciated. Thanks.
Many LG Blu-ray player owners experience frustration when they try to play downloaded movies directly from a USB drive, only to find that the files are not recognized or fail to play properly. This compatibility issue stems primarily from format mismatches: LG Blu-ray players support a specific set of video codecs, container formats, audio codecs, and subtitle types. Most downloaded movies use modern formats such as H.265 (HEVC), MKV containers with DTS audio tracks, or ASS/SSA subtitles, which may not be fully supported on all LG models. Additionally, USB drives formatted with unsupported file systems or video files exceeding the player's resolution and bitrate limits can further prevent successful playback.
The good news is that this problem has a straightforward solution: convert your video files into a format that your LG Blu-ray player can natively understand. By transcoding incompatible videos into the player's preferred specifications, you can enjoy your entire media library directly from a USB drive without any playback issues.
LG Blu-ray players have relatively standardized support for USB devices (USB flash drives, external hard drives) playback. The table below shows commonly supported containers and codecs across various LG models:
| Container (File Extension) | Video Codec | Notes |
|---|---|---|
| MP4 | MPEG-4 AVC (H.264), H.265 (HEVC) on 4K models | Best compatibility; supported by almost all LG Blu-ray players |
| MKV | H.264, H.265 (HEVC) on some models | Note: LG has limited audio support for MKV (often needs AC3 or AAC; DTS may not decode) |
| AVI | MPEG-4 (DivX/Xvid), Motion JPEG | Widely supported, but high resolution or high bitrate may stutter |
| MPEG-2 PS/TS | MPEG-2 | Common in digital TV recordings; extensions .mpg, .m2ts, .mts |
| AVCHD | H.264 | HD format from camcorders; playable directly |
| WMV | WMV9 (VC-1) | Supports Microsoft format, but DRM-protected files cannot play |
| MOV | H.264, MPEG-4 | Commonly supported on newer LG models |
| VOB | MPEG-2 | DVD video format; supported on most models |
| FLV | H.264, Sorenson Spark | Flash video format; supported on many LG players |
| 3GP | MPEG-4, H.263 | Mobile video format; supported on select models |
| DivX | DivX 4/5/6 | Requires DivX-certified models (most LG models are certified) |
| Xvid | Xvid | Usually supported together with AVI; equivalent to MPEG-4 ASP |
