seams the answer to the DTVPAL DVR,

Most Humax products, including that one, are intended for the Asia and European markets. Those markets use different standards for OTA and satellite. Humax does not offer any U.S. compatible HDTV recorders.

i think this one os for the US market because if you pick the US web site on the map this is the only model shown

No, the specs you pasted said 576p/576i. These are PAL resolutions, not NTSC, so it's definitely *not* a US-spec device. Sorry, but at least as is, this will not be coming to the US; the last Humax device I knew of that was sold int he US was a Humax TiVo DVR+DVD-R unit, and that was probably 5-10 years ago now.
