Would love help with the Swap function! We are having difficulty with the "Swap" function. With our prior Motorola DVR boxes, each box had 2 tuners that ran independent of the other, so when nothing was recording, you can watch something on one channel call that Tuner 1 , swap, then browse the channels on Tuner 2, and then swap back to the original programming on Tuner 1 which is a very cool feature!!! It appears the two tuners built into the box do not run independent of each other. I had read on line that a possible solution was to have the hard drive for the CISCO box be configured as "always on" which is not the default.

Sam Kear Hardware My Samung cable box recently stopped working and had to be replaced. When the Time Warner technician arrived I expected he would replace the box with an identical model but instead he left me a Cisco HDC box. Currently there is very little information available regarding the HDC cable box. Front Panel One of the cool features of the is the touch panel on the front of the unit. To activate a feature you can simply touch the text labels.

Guide — Brings up the on screen program guide. Info — Displays information about a selected program in the guide. List — Opens the list of recorded programs.

Exit — Exits the program guide or other menu. Select — Opened the highlighted item in the menu. Back Panel The rear panel design of the is pretty clean. The box includes a decent selection of input and output connections. The cable card slot is located on the upper right side of the back panel. Ethernet — Used for connecting the DVR to a home network. This is the best available connection on the The DVR I examined had this port disabled through the firmware image. Firewire — Used for sending video output to a firewire device.

Power for the DVR is provided by an external power brick manufactured by LiteOn, part number Using a watts up power meter I measured an actual draw of about 20 watts while the DVR was powered up. In sleep mode power usage drops down to about 18 watts. When enabled sleep mode activates after 4 hours of inactivity.

To enable or disable sleep mode press the settings button on the remote and access the timers tab. Highlight power save mode and press select to toggle the sleep mode on, or off.

The power adapter has an efficiency rating of level V which is currently the most efficient rating on the scale. There are 3 screws on the back of the box and 1 on each side that must be removed to remove the cover. Once all the screws are out pull back and lift up on the cover to remove it.

Under The Cover Removing the cover provides access to the hard drive and mainboard of the box. The cable card can be removed but it requires breaking the tamper evident seal to do so. Internal Hard Drive The hard drive caddy can be removed from the chassis by taking out the 4 gold screws holding it in place. The lower operating temperature of the drives leads to longer life spans. They are also designed to keep the power draw levels to a minimum.

After removing the screws the panel can be popped off, be careful not to break the clips. The touch button functions are printed directly on the board. It sits behind the plastic bezel hidden from view which makes it pretty difficult to locate unless you take the front panel off.

The plastic is actually semitransparent allowing the signal to pass through the front bezel to the receiver. The infrared eye is the black box on the right side. Diagnostics To access the on screen diagnostics hold the select button down for 15 seconds, then press the channel up button. After performing this key sequence the main diagnostics screen will load.

The summary screen show below displays basic status information about the cable box. The manufacturer diagnostics section contains 42 pages of diagnostics information. My provider Time Warner did not have a password configured to protect this page.

Page 30 of the manufacture diagnostics displays the current OpenCable middleware image loaded on the box. From the image file name you can see that the eSata port is disabled in this version.

Ethernet Support I connected the ethernet port on my cable box to a linksys switch and I was able to obtain link. The diagnostics pages indicate that the ethernet port is disabled. So far the only item I have been able to obtain is the quick reference guide. The box runs very cool and quiet which should provide a long life for the hardware, especially the hard drive. Although they are some nice cable management systems available such as the Blue Lounge cable organizer.

Also if anyone has access to a manual, or any other documentation for this box please contact me.

Mokree Lots of useful info. My reason for trading my Scientific Atlantic box in had to do with Olympic coverage issues, many issues. I would rather have my Samsung box back and deal with the voice not matching the picture than the terrible picture quality with this box. Would like to upgrade to a WD 1 TB but have had no luck.
