Media Manager slide show timing help

[Kasism]

Hi,

Not sure which forum this belongs but I have built multiple slideshows on my vista 32 machine using media manager.  I added music in the back.  When shown on my pc the slide show takes the timing settings I gave and runs perfect.  However when I go to the tv, the timing is fixed at 5 sec.  What can I do to adjust the timing?  Also, is there a means to play in a loop?  I have a music file with slide show I want to use on my large video wall during a party and want it to set to loop (100+ slides).  Thanks for any help!
