How do I setup an automated EPG downloader for ATSC OTA guide info, instead of just limited PSIP?

Ok, I have a Hauppauge 955Q ATSC USB tuner for my Mio. It automatically downloads PSIP guide data by itself, which is only good for like 24 hours. To do that however, you MUST click on each channel every 24 hours, and sit on it a little while to get it to load new data. IMO, that's too much work.

I found this program: [Only registered and activated users can see links. Click Here To Register...] which you can download, and once you have an account at Zap2it.com for your local channels, running that program script will log into your account to that internet guide, download 7 days of guide data, and automatically create an 'xmltv.xml' file. I'll attach a copy of that file here if you want to look at it. Notepad++ works fine.

How would I integrate this into the Mio's ATSC guide, so it could do this download and load this in place of the PSIP guide? Is it possible, or is there a better way to do it? Or at least enough hints to maybe figure it out?

I'm still running NA SatDreamGr image.

Thanks!
