Yeah, the government program-approved DTV boxes are super bare-bones and not really something worth hacking on. The most featureful one available at this time is made by Scientific Atlantic. I saw a very nice feature comparison of all the available coupon-redeemable boxes on AVSForum not too long ago. Might wanna have a look over there. Secondly, don't count on your coupons actually working. That program's outta money and the last couple of folks I've seen try to redeem their coupons at stores were SOL.

People that can't use grep properly: cat'ing a file and piping it to grep is completely unnecessary. Ditto grep'ing a file for a particular string then piping that to wc for a line count. Grep does both, and can save you a ton of typing.
