Hi all, After drawing a blank with Slingmedia support about watching full screen (and/or) landscape tv on my Treo 750 (Windows Mobile 6) I have come up with a solution albeit a little clunky but it works !.
I've installed NYDITOT Virtual Display http://www.nyditot.com/Home.asp It lets you set your Treo to any resolution, any orientation, and have the ability to zoom into any part of the display, So I set landscape, zoom 150% and then pan into the tv picture area of Slingplayer Mobile using the 'D' pad. And you end up with a full screen correct aspect ration tv picture, which is all I wanted in the first place. Other fun to be had with this product are surfing the web at 640 x 480 landscape on the Treo screen, or looking at nearly three times the usual spreadsheet columns. I've pinned the 'VD Menu' to the Start Menu for easy access. I've only been trialling it for an afternoon so far but it seems good value at $19.95 Regards, Mike Dyer.
