Zooming the picture stretches it incorrectly

[F J Walter]

When zooming using the "Pan and Scan" feature, the picture stretches in the horizontal and vertical direction by different factors. This creates picture which is too narrow or wide at any setting other than the original.

 

- Zooming out makes the picture a little too short and wide.

 

- Zooming in makes the picture a little too tall and narrow.

 

It appears that the horizontal and vertical dimensions are changing by the same linear amount, where they should be changing by the same ratio. So, when zoomed all the way out, the picture becomes a short horizontal line because the picture reaches zero width in the vertical direction before it does in the horizontal direction. It should remain the same shape, and only the size should change.

 

The only way around it at the moment is to adjust the horizontal and vertical stretching amount separately, making sure you adjust the horizontal stretch more than the vertical stretch.

 

Here are my system specs:

 

# Windows XP Professional

# Using Cyberlink MPEG-2 Decoder and Cyberlink AC3 Decoder

# ATI Radeon 9600XT video card with latest Catalyst drivers

# Using DVBViewer 3.6.1.20 (latest version)

# ASUS My Cinema U3000 Mini (tuner, using latest WHQL driver from asus site)

# Using 'Overlay' mode for directX

# Problem exists with all default setup options

# Watching PAL signal (720x576 widescreen)

 

Sorry if this has already been reported - I couldn't find it

It looks like this problem is most noticeable when the source is in 16:9 format and you are watching it full-screen on a 1280x1024 LCD monitor.
