DVD refers to the disc on which one can record. Yes, a TiVo with a DVD burner can burn DVDs. Yes, you can burn just about anything that's recorded and later put the DVD into your DVD player or TiVo DVD unit and watch it. It is great for archiving stuff.
The TiVo DVD burning units (e.g., Humax and Toshiba) burn DVD-RW or DVD-R discs. The -RW you can rewrite many many times. The -R are one time only. The -R discs are much cheaper, but if the burning fails, you have a coaster. You CANNOT use +R or +RW discs.
Your pricing estimates are high. I recently got 50 Ridata DVD-RWs for $28 from amazon... best price I've seen I much prefer -RWs because I can rewrite the discs... that means if a burn fails, I haven't lost anything because I can try again. Also, if I decide I really don't want to keep a bunch of sitcoms or trashy movies around, I can reuse the disc.
Some people have purchased inexpensive DVD burners and attached them to their current TiVos... that's fine, and is more flexible, but the convenience of an all-in-one system is great. Plus, the TiVo units burn the DVD with a TiVo style menu, which works quite well.
Don't sweat missing out on that deal... there will be plenty more, just look around and see what's out there. Plus, there are very good rebate deals on new units, too.
Hope this helps and post more questions as needed!
