I have a RCA F38310 HDTV which has a YPrPb input for HD only. (The set has it's own HD receiver built in.) I loaded the latest software and cannot get the setup to switch to the YPrPb setting or chand the settings for crop, fill, or normal. I am using 1920x1080i for my resolution. Can anyone tell me if you have to load all of the software revisions all of the way to the newest one or can you just install the new Beta version as a clean install and be up and running. The system was working fine when I was using the software included on the CD which came from the manufacturer.
