I have the Philips HDRW720 and had identical TV Guide issues. I talked to the Philips people and the TV Guide people. It seems that the problem is with the cable companies. My company is Brighthouse (Time Warner) and they had compatability problems with the TV Guide program as recently as September 2005 here in Florida. At time there would be no data or missing data. I tried to record programs but there would be nothing because the cable company was not transmtting the data. It has improved 100% since I bought my recorder, still not perfect but almost there.
