It's that time again -- you know, the moment when San Antonians that rely on Time Warner Cable (partly owned by Time Warner, parent company of AOL, which owns Engadget) can look forward to even more HD channels when they flip on the set. TWC has been doing its part to add a (small) number of high-definition stations of late, including a few here in the Raleigh market this month, and those dwelling in south-central Texas should now be able to view the Lifetime Movie Network (LMN), Food Network HD, HGTV HD and The History Channel HD. We know, it's not the most enthralling list of additions, but hey, we'll take what we can get.
