How DVR-MS turns into FLAC: audio-stream extraction
Only the audio stream inside DVR-MS is pulled out - The picture stream is discarded entirely - And encoded as FLAC. What comes out is genuine audio, never a muted copy of the video. DVR-MS input is demultiplexed as a recorded-television program so broadcast timestamps, language tracks, captions, and guide metadata can be inventoried separately. FLAC output losslessly codes decoded samples and supports rich comments, yet it cannot reconstruct fidelity already removed by a lossy source codec.
Decoded media - A Microsoft recorded-television container carrying broadcast streams plus program metadata. Encoded delivery profile - Losslessly compressed audio that preserves decoded samples and supports rich tags.

DVR-MS source facts versus FLAC output requirements
What can fail when DVR-MS video container is interpreted
Protected recordings cannot be converted normally, and subtitles, guide data, multiple audio tracks, or timestamps may be lost.
What Free Lossless Audio Codec cannot safely promise
FLAC does not make a lossy source lossless again, and some basic players reject less common sample rates or channel layouts.
How the FLAC writer handles this route
The verified FLAC profile uses lossless compression level 8; it preserves decoded samples rather than source codec data.
Acceptance evidence for the converted FLAC
Record the DVR-MS evidence before conversion
Confirm authorization and inspect program duration, stream count, captions, audio languages, sync, seeking, and recording metadata.
Test the FLAC file in its receiving workflow
Compare duration, sample rate, channels, peak levels, and tags with the decoded source.
Deciding when DVR-MS to FLAC is the right conversion
Take this route when only dialogue, music, or a soundtrack needs to reach a FLAC-accepting system; hold onto DVR-MS whenever its pictures, captions, or visual timing still matter.
What changes between the DVR-MS model and the FLAC deliverable
- The source stores a Microsoft recorded-television container carrying broadcast streams plus program metadata; the destination stores losslessly compressed audio that preserves decoded samples and supports rich tags. Compare application metadata after that structural change.
- Treat DVR-MS-specific metadata fields as optional in the FLAC result until you have actually confirmed they survived.
