I bought a brand new HDTV (Full TV). So it's native resolution is 1920*1080. I only have 2 HDMI ports. One for cable box, the other one for DVD player. So I can't use HDMI for my mythtvBox

I was wondering if I could plug my mythtvbox with S-video cable using 1920*1080 or not.

My video card is a nvidia Fx 5200.

Is it possible?

Otherwise I have a VGA port. Can it do the trick?

Defiantly won't be able to use the SVid for HD. It is for SD only.

You *may* be able to use the VGA, depending on the TV. If you have a DVI port your best bet would be to use a DVI->HDMI adapter.

Some more info might help to pin it down a little better.

Just a thought - How well does KM play DVDs nowadays? Maybe it could replace the separate DVD player.

<--Is your location in your profile? Why not?

With the nvidia cards/drivers at least, whatever resolution you use with X gets mapped to the NTSC or PAL resolution for s-video output. The worse the match is the worse the display will look, but it'll never be better than that SDTV bottleneck.

(NB.. please correct me if this is rubbish.)

to me this means that ideally you'd use 1920x1080 for X and get a video card with a hdmi output. If your input is 1080 you'd not do any scaling and get the best possible output.. variable input resolutions (for example watching a dvd) would be scaled once by X, and be suitable for your tv.

VGA was analog... HDMI is digital. You can get a VGA>HDMI adapter - which will presumably work.. but im guessing a loss of quality.

If you keep with the s-video, i'd use NTSC resolution for X, tune to SD, and let your tv scale to HD. once again the video is only scaled once, but this time by the (potentially crappy) scaling chip in the tv. obviously this defeats the purpose of using a HDTV so <$100 for a new video card is well spent.


The mythvideo internal player will decode the dvd using the mythtv TV playback settings.

thank you guys for your answers.
Forget about HDMI. All my ports are already used.

So the only choice I have is to use to connect my MythtvBox with DVI port to the VGA port of the TV. I'm gonna forget S-Video.

Even if there is a loss of quality, it's possible to get 1920*1080 with this method. Or will the X resolution be less and the TV will upscale the signal?

I read that the max resolution through VGa was 1600*1200.

Do you know what the max supported resolution your TV supports over VGA? A lot of TV's for some reason limit you to 1024x768 over VGA. VGA will support 1080 video, if your TV can handle it.

My tv is a HDTV, so I thought it could handle 1920*1080 over VGA as well.
It's a samsung LN-T4061F. I'm gonna look the specs.

I'm confused. Why are you not using DVI to HDMI?
I thought the idea of a Myth box was to converge all those different bits of kit into a single unit?
Therefore, you don't need the DVD player and only the cable box. Can your calbe box feed both myth and your TV? Or Is your Mythbox controling the Cable box?
I use Myth to watch my DVD's and now my modeline and TV are about right I have very few issues. Or is the DVD a HD-DVD player?

Actually, I tried to use my Mythtv Box as a DVD player (long time ago R5A16 or less don't remember), but it didn't play very well. Xine was buggy and I didn't succeed to set up my SPDif output. (via chipset)
Sometimes it didn't play my DVDs at all. (Yes I enabled css something , don't remember exactly what it is).

Now, I'm using my mythtv box as a DVR which controls another hidden cable box.

That's why, I'm using a separate DVD player.

I'd like to change my DVD player because I hate it. So maybe it can be the time to give my mythtv box a second chance to test it as a DVD player. I'd like to have a DVD player 1080p compatible. I guess mythtv can do this easily!

My config will be very complicated. I want to use MythMusic and MythDVD with SPDIF output (plugged into my amp) and Recording, Live TV with 3.5 jack output (plugged into my TV). Is it possible (Maybe another thread somewhere).

PC Maximum refresh rate (at 60 Hz) 1920 x 1080. good it handles it.

I guess , DigitalAudio in the Wiki will help!

I use SPDIF out over optical for everything... live TV, recordings. However, my amp upmixes everything or uses Dolby/dts intelligently... it might not be so attractive if yours doesn't.

I don't want to use spdif for live tv and recording. But I saw something really interesting in the WiKi. Digital and analog in the same time.
I have to test.

Have you looked into getting a switch to handle more HDMI inputs?

Here are some examples:

yes ... you are right.
but tophee made me to try it again, so if it works I would have enough HDMI port.

I can use a DVI->HDMI in 1920*1080.

Will Xine upscale the signal up to 1920*1080?
Will my computer be strong enough to display a DVD at 1920*1080? It's not HD.

I can upgrade to a FX 6200 or something else if it helps
