Does anyone know if it is possible to get an anamorphic signal over S-Video with the Voom box?

Does this work with the DVD recorders on the market? (anyone tried?).

Thanks...

I do it with my Sony RDR-GX7 all the time and it works great. I have svideo coming from the Voom STB. If you want to do some research on other DVD recorders I'd suggest you check out www.avsforum.com on the boards under DVD recorders. There are some very knowledgeable people there. Good luck!

What Voom settings are you using to get the "anamorphic" version of the video? Or are you just recording standard 4:3 letterbox?

Maybe I should clarify - anamorphic is where the entire 16:9 image is compressed down to 4:3 (everyone looks thin).

Most 16:9 tv's read this as "DVD", and re-stretch the screen for you.

Letterbox is a 16:9 image shrunk down to fit a 4:3 screen (with black bars on the top and bottom). Letterbox loses resolution when the 16:9 tv stretches it (it has to stretch both the horizontal and vertical, instead of just the horizontal in anamorphic).

So, are you recording anamorphic or letterbox?

Thanks!

Maybe I misunderstood the term anamorphic. I set my GX7 to record in 16:9 mode (but it can only do this up to 2 hours record time). I have my Voom STB to output a 16:9 image to my HDTV. When I playback the image on my 16:9 HDTV the image is exactly the way I viewed it (this is expected). When I played the DVD in a non-HDTV 4:3 TV the image did not look compressed or skinny. It looked normal. My understanding is the GX7 can set the 16:9 flags correctly and that is the key.
I'm not sure if I answered your question, but I advise you to check out the following link. I think this covers it well.

Hope this helps.

There is a program ava from doom 9 that is supposed to change the flag in your vob file before you burn, I cannot remember the name at this time.(only if you burn with a pc)

Basically, my thought is to get my ReplayTV to record in Anamorphic. Then, on my Sony LCD TV, I can use the standard "stretch" zoom, which only stretches the horizontal (and leaves the vertical alone). This will result in a better 16:9 picture than using the standard "zoom" mode, which stretches both horizontal and verticle.

I found an option in the Voom setup to squish a 16:9 image over the s-video. I'm going to try it tonight. I'll let you know how it works out...

Until then, here is a good article about anamorphic and it's history...

Well, I found out in the resolution settings on the voom box, you can "squeeze" 16x9 video into a 4x3 format (called Anamorphic).

It actually works great. It allows me to record the entire 16x9 image on the 4x3 replaytv. Then, when I play it back using the Replay, I use the "zoom" function on my sony widescreen, and it stretches it back to 16x9. This is exactly what I wanted.

As for the resolution, it is still 480i. However, when I stretch widescreen movies recorded in Anamorphic, they look much better than just scaling the 16x9 to fit on a 4x3 screen (scaling both the vertical and the horizontal), then playing it back using the "full zoom" function on my tv. It's just sub-DVD quality to me - so it is acceptable.

One issue though, is that when you set the Voom receiver to output in Anamorphic it only squeezes 16x9 video - 4x3 video is left untouched. So, when I watch programs using my replay, I need to constantly switch between zoom and regular (as the programming switches between anamorphic and standard 4x3 video). Somewhat of a pain, but acceptable until the PVR comes out. Also, the funny thing is that regular OTA signals are "squished", even though the majority of the programming in upconverted 4x3. So, it gets a little confusing once it's recorded.

Obviously, it's not a HD solution - but one that will make the recording of 16x9 look much better.

I do it with my Panny E85H, though it is FAUX anamorphic. What I do is set the Voom stb to output a vertically stretched image in the 4:3 setup screen and my Panny records it that way. When I go to burn the DVD, the Panny will only record in a 4:3 format and warns me of that since it recognizes the anamorphic pic. But when I play it back through the player and select FULL on my pj, it fills the entire screen just like an anamorphic DVD.

That is an excellent tip to be aware of. Until I can record real HD, I am trying to optimize the PQ every way I can.
