I don't have the remote, so I'm using my mouse and the onscreen control pad to control DVD playback on MCE 2005.  I've been generally disappointed with the controls.

 

I've set the channel buttons to skip chapters, but each time I press a channel button, it skips 2 to 4 (typically 4) chapters. 

 

Does anyone have any suggestions as to how I might fix this and, more importantly, is anyone aware of a way to modify mouse controls of the DVD playback (e.g., with the Roxio DVD player on my old computer, I could search at different speeds using my mouse wheel)?  Is there anyway to modify the control panel?

 

Thanks in advance.
