What is a DVR file?
The DVR file extension typically denotes a proprietary video container created by consumer Digital Video Recorders (PVRs), CCTV security systems, or satellite receivers (e.g., Dish Network). These files often encapsulate an MPEG-2 Transport Stream (TS) or H.264 video stream, but they are frequently wrapped with proprietary encryption, metadata headers, or non-standard indexing to prevent unauthorized playback or export. Unlike the Microsoft-specific .dvr-ms format, a generic .dvr file strictly strictly adheres to the vendor-specific implementation of the recording hardware.
How to open a DVR file
Due to proprietary encryption and lack of standardization, .dvr files rarely open natively on Windows or macOS. Playback usually requires the specific proprietary software provided by the hardware manufacturer (e.g., the security camera vendor's viewing client). In some cases where the file is an unencrypted Transport Stream, VLC Media Player or PotPlayer may be able to force playback by treating the file as a raw MPEG stream.

What is an AAC file?
Advanced Audio Coding (AAC) is a lossy digital audio compression standard defined by ISO/IEC 13818-7 (MPEG-2) and ISO/IEC 14496-3 (MPEG-4). Developed by a consortium including Bell Labs, Fraunhofer IIS, and Dolby Laboratories as the successor to MP3, AAC utilizes the Modified Discrete Cosine Transform (MDCT) algorithm and perceptual noise shaping to discard imperceptible signal components. It supports up to 48 audio channels, arbitrary sample rates, and utilizes extensions such as Spectral Band Replication (SBR) to achieve higher fidelity at lower bitrates than predecessor formats.
How to open an AAC file
AAC serves as the default audio container for Apple's iTunes and iOS devices, ensuring native support within the macOS Core Audio framework and Apple Music. Windows 10 and 11 provide native decoding support via the Groove Music and Windows Media Player applications. For cross-platform playback or advanced stream analysis, users should utilize VLC Media Player or FFmpeg, which contain the necessary libavcodec libraries to decode AAC streams without external codec packs.
