rbinck,

I have a cable, one side is S video and the other side is RCA. The s video side connects to the Nvidia S video port and the other end to the RCA input on the TV.

I also have a VGA to rca cable. Do i need a convertor or something ?

Is the RCA end only a single RCA plug? Where did you get the cable? Did it come with the video card?

They do make VGA to composite converters like this one: PC To TV Video Converter by LKV-2000

rbinck,

The RCA end has to two RCA plug's. I had a very old creative capture card probably 10 yrs old it came with it.

But i tried with this cable too but no output.

But is it necessary to use this PC TO TV VIDEO Converter ?

s-video is two signals that is combined to make composite. The two RCA cable does not combine the two signals. That is probably a cable that can only be used with the card it was made for. You need a different adapter like this one: S-VIDEO (VHS) Male TO RCA Female Adapter - Gold Plated
Plug that into the PC video card then use a male-male RCA cable to the tv. For sound you will also need a stereo audio cable.

rbinck,

But the cable i have is Svideo to RCA (single). My display card does not have a RCA output but a Svideo output and the TV does not have Svideo input but RCA input.

I tried this. I connected the Svideo cable to my DVD player and the RCA pin to the TV in and no display so i guess my cable is faulty.

The other thing. I have DVD movies with surround 6 channel (5.1). how would that work on the TV (my denon av receiver is damaged) as the TV would only support stereo can i use the sound card of the comp for the surround ? if yes then how can I configure that ?

Sounds like the cable is bad. To get surround sound you need a decoder of some sort. Some sound cards have a built in decoder and will have the 5.1 outputs for connecting to a 5.1 amplifier. Otherwise if the sound card is just stereo then you would need to use a Dolby Pro-Logic decoder/amplifier.

rbinck,

All my sound cards are 5.1 (Creative SB) and Realtek ALC655.

In fact my main comp has two sound cards (SB 5.1) and (Realtek 5.1) and i can use both of them together.

I am really confused about Dolby. Does it mean if my sound card is a 5.1 it will have a Dolby decoder ?

I use the MPC-HC player for video.

I have a video file and the media information shows as AC3 - Dobly Digital with 2 channels. Does it mean that it is only stereo ?

If your sound card has separate outputs for left, right, center, left surround, right surround and subwoofer then those outputs would connect to a 5 channel amplifier (or 5 amplifiers) plus a powered subwoofer. It is doubtful that those outputs would run the 5 speakers without an amplifier.

I does sound like your card has a built in decoder. To know what to advise I would need the model number of the Soundblaster card. The Realtek ALC655 is the 6 channel CODEC supported.

There are two methods for getting 5.1 audio out of sound cards. One is the five individual outputs described above and the other is via spidif you first inquired about. The spidif connection is digital audio and requires an external decoder/amplifier.

rbinck,

My Denon AVR is badly damaged so my options are currently limited to my sound card. The creative sound card model is SB0680 - SB 5.1 PCI . Earlier i had the SB Live but it has shorted out. Well i think the Realtek does have Center / L / R / SL / SR , though in the volume control it shows an option for a subwoofer it has only output ports. Also the SPDIF is on the motherboard so i need a connector for it.

Currently i am using my 2 set's of ALtec Lansing 2.1 speakers as 5.1, 1st set Front Left/Right/Sub-woofer and the 2nd set as Rear SL/SR and the sub woofer powered down. Connected Altec 2.0 speaker to the center and they all are performing real well . I have to buy a surround set for the comp so i am looking at AL 5051.

On the MPC-HC i have a an AC3 filter which decodes. If you have any knowledge please do let me know.

Sounds like you got it figured out for now.

rbinck,

Yep for the moment. I have bought a new Svideo to RCA cable hope it works.

The new cable works well.

Do you have any idea about the AC3filter (i use it under Media Player Classic ), i am confused regarding the output settings.

1 ) 3/1+SW 4.1 surround

2 ) 2/2+SW 4.1 quadro (on selecting this it shows output on the center channel)

So what is the difference between these ?

rbinck,

I can not figure this out. when the audio stream is lossy it would mostly be a mp3. Certain movies which i have shows audio as mp3 having 2 channels. OK, this you may not know or may . So when playing these video''s , Under the AC3filter it shows input channels as Sub / L/R/SL/SR and so does the OUTPUT show the same. If the audio has only 2 channels then why would it show this type of an INPUT & OUTPUT ?
