1. A computer-implemented method for content playback and recording, comprising:

  • reading, by one or more processors, media content from a digital versatile disc (DVD) at a first rate that is a multiple of a standard playback rate of the DVD, wherein the media content is subdivided on the DVD into one or more cells, each cell comprising a plurality of sectors, and wherein reading comprises;

    in response to encountering an unreadable sector, incrementing a bad sector counter for a cell containing the bad sector;

    in response to encountering a readable sector, clearing the bad sector counter; and

    in response to the bad sector counter exceeding a predetermined threshold value;

    marking the cell as a bad cell, such that subsequent reading of the cell is not attempted; and

    skipping to a next cell to continue reading the media content;

    storing, by the one or more processors, the media content in a hard drive concurrently with reading the media content at the first rate; and

    playing back, by the one or more processors, the media content from the hard drive concurrently with the storing the media content, wherein the media content is played back from the storage device at a second rate that is the standard playback rate of the DVD and slower than the first rate.
