Anyone here have any experiences using these devices? I was wondering for example if they really made an improvement say for viewing a VHS movie?

I have not used these particular devices. The purpose of up-conversion is to allow newer and likely more complex equipment including monitors access to older source material. Broadcast networks up-convert lots of NTSC analog source to make HD program material. This should be noticeable to the discerning viewer. It surely is to me--a broadcast engineer. If the ouput of a vhs player looks better on a vga monitor than a television set with same tube sizes and viewing distances, it is likely that the up-converter removed noise from the signal. It would be less expensive to get a video processing amplifier.

Bona fortuna.

Hey thanks for the info. I think I'm going to buy one of these devices (my Christmas gift). I have read a couple of reviews and it seems they really do improve the picture quality.

A line doubler does just that, it doubles the lines of resolution and it's application used to be for the presentation/projector world. The line doubler has pretty much been replaced with the scaler which does more than increase resolution, for example, the better ones convert interlaced material to progressive material and can adapt to any native resolution device.

We use scalers all the time when we design video distribution systems that combine computer presentations with regular video.

Line doublers are pretty much a thing of the past.

As always, you get what you pay for. Most scalars that we specify in our designs are $2,000US or more. Anything under $500US would probably not do you much.

I am also interested about the AVT-3800.

Anyone using it?
