[mythtv-users] OT: How to submit form, retreive web page and save it to a file?

[William]

I am preparing to write a ppv listing utility for Dishnetwork and I am
stumped as to how to pull the info I need from the provider's web site. What
I need to do is to be able to fake the submission of a html form and then
retreive the data returned. I don't think that 'wget' supports the ability
to send form data and I didnt see any command line hooks into Mozilla.
Please correct me if I am wrong on the above programs.

How would you go about this data retreival process? 

I can do all the processing in windows pretty easily but I would prefer to
keep it pure Linux so everyone can use it.

TIA,
Bill
