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.

Abstract
A method for content playback and recording may include using a computer to obtain media content from a recorded medium. Concurrently with obtaining the media content, the method may include reencrypting the encrypted media content using a secondary encryption key and storing the reencrypted media content in a storage device.

6. A system for content playback and recording comprising:
-
a digital versatile disc (DVD) reader for reading media content from a DVD at a first rate that is faster than 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 the DVD reader; in response to encountering an unreadable sector, increments bad sector counter for a cell containing the bad sector; and in response to encountering a readable sector, clears the bad sector counter; in response to the bad sector counter exceeding a predetermined threshold value; marks the cell as a bad cell, such that subsequent reading of the cell is not attempted; and skips to a next cell to continue reading the media content; a hard drive for storing the media content concurrently with the reading of the media content at the first rate; and a playback device for playing back the media content from the hard drive concurrently with the storing of the media content on the hard drive, wherein the media content is played back from the hard drive at a second rate that is the standard playback rate of the DVD and slower than the first rate. - View Dependent Claims (7, 8, 9, 10)

11. A computer-implemented method for content playback and recording, comprising:
-
reading, by one or more processors, blocks of media content starting from a first location of a recorded medium at a first rate, wherein the media content is subdivided on the recorded medium 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; concurrently with reading the media content; storing, by the one or more processors, a copy of each block read from the recorded medium in a storage device; marking which blocks of the recorded medium have been stored in a data allocation map; and playing back, by the one or more processors, the media content from the storage device at a second rate that is slower than the first rate. - View Dependent Claims (12, 13, 14, 15)
