He's either referring to the LG 3410a HD DVR, which uses the free, TV Guide on Screen service, or an SD HDD/DVD recorder they had out a couple of years back that got it's Microsoft-based guide info from the internet. There originally was a subscription fee for the guide, but by the time they started knocking the price way down to clear it out, they also dropped the subscription fee entirely. I don't know if the service is even available anymore. It could be.
Panasonic stopped making HDD models before this year (SD-only) - but you can still get "multi-regional" or "international" models if you know where to look (www.world-import.com
carries them). But the warranties are only for like 30 or 90 days, and they only have analog tuners (which won't matter if you're using an external one). Pioneer has a few of these type models, also. People here who have bought them have been mostly very satisfied with them, as Panny and Pio generally have always made the best SD HDD/DVD recorders. I know that at least the Pio's (if not both brands) have TVGOS, but I really don't know if it works in this country - although I don't see why it wouldn't. They also have some pretty large hard drives in them (up to 400 GB).
Otherwise, finding an older model used is your only choice. And you never know what you're getting with ebay. Occasionally an HD or SD unit will pop up in the "For Sale" area on this forum (mostly because a person just caved in and got the TiVoHD, which has finally become reasonably affordable, especially with the 3-yr. pre-paid subscription - about $8.30/mo.), so you can check that once in awhile, also.
Check over in the "HDTV Recorders" sub-forum for information on the HD subscription-less DVR's, and the "DVD Recorders" sub-forum for info on the SD ones. Most of the information on these types of units is concentrated in those two sub-forums. Sometimes people selling their older units will announce it in the threads there.
