Digital Video Recorder (DVR)
with OCAP Software DCX3510-M • User Guide 6
365-095-25385-x.1
Digital Video Recorder (DVR)
The DCX3510-M set-top is equipped with an internal hard drive for DVR (Digital Video
Recorder) functionality, which provides the ability to record both Standard-Definition TV
(SDTV) and High-Definition TV (HDTV) programs. Storage time varies based on the video format
and specific channel.
DVR offers the ability to control your viewing experience by pausing (time shifting) live TV and
providing trick playback modes (pause, fast forward, slow forward, fast rewind, slow rewind).
You may experience a slight delay when switching between time-shifted and live TV.
The DCX3510-M model also includes integrated MoCA™ networking which supports whole-
home DVR capabilities. This feature extends the DVR experience to DCX3200-M or other
compatible non-DVR set-tops with integrated MoCA, when enabled by application software.
On your non-DVR set-top you can now view your DVR recordings, playback content, and set
future recordings from another room in your home.
With the DCX3510-M set-top, you can:
•Record Programming. The DCX3510-M is equipped with a 500 GB storage drive which
can record 160-300 hours of standard-definition programming, or 40 to 60 hours of high-
definition programming. These capacities are based on recording digital MPEG-2 video. A
recording of a video program that is broadcast in digital MPEG-4 format requires
approximately half the disk space.
•Maintain a Personal Program Library. Use the Interactive Program Guide (IPG) to access
your library.
•Control Live TV. Pause, rewind, replay and fast forward live TV.
•Simultaneously Watch Two Programs. Watch two programs and easily switch between
them using the swap key on your remote control (Dependent upon program guide
support and provided remote control).
•Simultaneous Watch and Record. Record one program in the background while viewing
another live broadcast at the same time.
•Simultaneously Record Two Shows. Record two programs from two different channels at
the same time.
•Simultaneously Record Two Shows and Watch a Recorded Program. Watch a program
recorded on your DVR while recording up to two other programs at the same time. You
can also easily switch from viewing the prerecorded program to either of the programs
you’re recording.
•Play Recorded Programming On Networked Set-tops In Your Home. Using integrated
MoCA networking, DCX3510-M recorded entertainment can be accessed by other
compatible non-DVR set-tops with integrated MoCA, when enabled by application
software.

Using the External DVR Expansion Feature
To use the external DVR expansion feature of the DCX3510-M, first ensure that your service
provider has authorized your DCX3510-M for external DVR functionality. If authorized, follow
these steps to begin using the external DVR feature:
1. Power on your DCX3510-M and your television and ensure that you have a picture.
2. Connect a compatible eSATA hard disk drive to the DCX3510-M using the eSATA cable
supplied with your external drive enclosure. The DCX3510-M will automatically detect that
a hard disk drive has been connected to the eSATA interface.
3. The DCX3510-M displays an alert that an external hard disk drive has been connected and
that it must be formatted. Use the remote control to confirm the format (formatting a drive
erases any and all content that on the drive).
4. The DCX3510-M displays a message when formatting is complete and if the operation
succeeded or failed.
During formatting of the external hard disk drive, the DCX3510-M performs several tests to
determine if the hard drive’s performance is acceptable for DVR functionality. If the hard drive is
unable to pass these performance tests, the DCX3510-M alerts you that the external drive is not
compatible for DVR use.
5. The DCX3510-M confirms that an external drive is connected and available for use.
While using the external DVR expansion feature of your DCX3510-M:
•Recordings made on the external hard disk drive can only be played back on the same
DCX3510-M used to record the programs. You cannot connect your external hard disk
drive to another DCX3510-M (or another cable box with an eSATA interface) and watch
programs that have been recorded on the hard drive.
•You can use multiple external hard disk drives with the same DCX3510-M, however; you
can only watch the recordings that are available on the drive connected to the DCX3510-M
at that time. To watch recordings that you made on another external drive, simply
disconnect the external drive, follow the on-screen prompts, reconnect the other external
drive, and again follow the on-screen prompts.
•Whenever the DCX3510-M reboots, a temporary loss of the program listings in the
interactive program guide (IPG) is possible.
