Why did you change the tv-guide scaling? The bars are very big now, the text within the bar is only half size of the bar and not centered vertically. Because of the bigger program bars there are less channels shown in one screen.
This is easy to adjust in MyTvGuide.xml:
Find this section:
<description>Channel template</description>
<type>image</type>
<id>20</id>
<posX>50</posX>
<posY>105</posY>
<width>256</width>
<height>42</height> <-------Change this height.
