Lite on 24x Questions

Hi sorry but new here. these might be silly questions
Just got a 24x lite on which works great so far BUT;) On Blindread and cdrwin and Fireburner all report NO sub channel data can be read!! Seems odd to me as the everyone on the forums says it can. Can any one shed any light? Or am i just stupid ahaha Got latest firm and latest programs too.

Also does anyone know what the jumpers to the left of the ide connector do?

Cheers all :cool:
