Solved How far can a Cisco cable box DVR push an S-Video signal?

Dell / Inspiron one 2320
September 29, 2013 at 19:09:45
Specs: Windows 7, 3.3 GHz / 4001 MB
I have one of these USB-TV tuners.

http://www.amazon.com/Encore-ENUTV-...

It has an S-Video input and software to record input onto the PC. My DVR box has an S-Video output. I want to try transferring some shows from the DVR to my computer which is in a different room.

Can a Cisco DVR box push the signal through a 15’ S-Video cable? How about 25’? With 25' I could run the cable through the basement for a more permanent installation.

Any idea on the quality I might expect? It doesn't have to be HD, it's just some woodworking shows and I want to save the tips and techniques they use for their projects.

Any thoughts on this matter would be appreciated.

The cable output will provide video and audio, the S-Video will only provide audio so you will have to run extra audio cables if you go that route. It might be more convenient to just run one cable line. S-Video might be slightly cleaner, I'm not sure about the file size. Before you run all the cabling you might try moving your computer in the same room, and using short cables try both and see which gives you the more satisfactory results.

I did some Googling and people have said they have run it upwards of 75 to 100 feet without problems. You shouldn't have any issues running it 25 feet or so. You would also need to run audio cables as S-Video doesn't carry audio.

What is the model of your Cisco DVR? Some DVR's such as TiVo will let you save programs to your computer via software through the home network.

Thanks for the response.

My DVR box is a CISCO Explorer 8640HDC.

According to TWC the only way to copy shows off of this DVR is to play the show through one of the outputs (component or S-video) into a device that can record the signal.

There's no copying of a file, there's only output and record.

Does your DVR have a USB port on it? I copied this from another forum, not sure if it's true or not.

Pop the flash drive into the usb socket on the front of the T-Box, then go to the recording want to export, and you will find that just above "play from the beginning" and "Export to usb device" option appears. Click on that.

THX 1138,

I just called TWC.

The USB ports on my Cisco box are inactive. The only outputs are Component, S-Video, HDMI and Cable Out.

The only way to move programs from the DVR to a PC or a DVD is via the play/record route.

Since I have about 26 half hour programs that I want to move, it's going to be a long, slow process since each one has to be done individually, with a manual start and stop at each device.

I should be able to use either Cable Out or S-Video to my USB TV tuner. Will there a difference in either file size or video quality based on which one I use?

Thanks!

Thanks.

Leaving the systems where they are and running cables as a test is not that big of a deal. It's really just a matter of running the cables from the living room to the family room across the width of the kitchen. Final installation would be almost the same thing except that the cable going though the kitchen would simply go under it. The access holes are already in place for other cable runs that I have.

I have more than enough coax and audio cable to do that (multiple times!) but I have no S-video cables. If I chose to test the S-video output, I'll probably just buy something long enough for the final installation. The prices at monoprice.com are cheap enough that it doesn't make sense to order a short cable just for testing.

Thanks again!

I would go with S-Video then. Using the video cable would mean the signal would need to be converted to RF then converted at the other end back to video and audio. This could cause degradation in the signal.

Good luck!

Just out of curiosity, what shows are you copying? I do that with Ask This Old House and New Yankee Workshop shows. My Tivo lets you save the video to your computer and I burn them to DVD's.

My main goal is The Woodsmith Shop.

Eventually I'd like to get all the Live From Daryl's House shows off the DVR also. Many of them are available on the web, so I need to sort through to see which ones I need saved.

Well, I did some testing today. As it turns out, the video is not going to be a problem, it's the audio.

I should start by saying that I've never thought the ENUTV-4 box had great audio when watching cable TV. It always seemed a little raspy.

The device will accept video input via cable, S-Video and an RCA jack. There's an audio-in jack for the S-video and the RCA inputs. I tried recording programs from the DVR via cable as well as the RCA input. In both cases the audio was terrible. Worse than the audio heard when watching cable TV through the device. The video was tolerable, but the audio is unacceptable.

Since the audio is fine when the programs are transferred directly to DVD and then played on the PC, the audio portion of the ENUTV box is obviously the problem.

Oh well, thanks for the suggestions but I guess I'll stick with using DVD's.

Sorry to hear it didn't work out for you. Tuner boxes are dirt cheap these days, have you thought about trying another brand?
