Here's an example zoomplayer screen. It has the basic 240x128 background image and text "Zoomplayer" on the first row. On the third row is the zoomplayer status message.
I only wrote this here and it's not tested but it shouldn't be that complicated so I hope it's correct. Also there's no transition to another screen from this one. For that you need to add <action> as described in the screen editing instuctions.
Code:
<screen>
<name>ZoomPlayer</name>
<item type="image" x="0" y="0">
<imagebitmap>screens\240x128\bg_nfo_240x128.bmp</imagebitmap>
<refresh>500</refresh>
</item>
<item type="text" x="0" y="0">
<scrolltype>none</scrolltype>
<textpos>left</textpos>
<fieldsize>10</fieldsize>
<textdata>ZoomPlayer</textdata>
<refresh>1000</refresh>
</item>
<item type="plugintext" x="2" y="2">
<scrolltype>none</scrolltype>
<textpos>left</textpos>
<fieldsize>15</fieldsize>
<varid>ZoomPlayer.Status</varid>
<refresh>500</refresh>
</item>
</screen>

I hope this would get you started. If there's any option you'd like more information about let me know.
