Time based recording problem ATI AIW 9000

I just installed an ATI All-in-wonder 9000 (Radeon). The card appears to work fine. The TV-cable picture is good and Guide Plus loads just fine. One touch recording works fine too. The problem arises when I try to record a program by using Guide Plus. It simply does not start recording at the time that it is supposed to. I went to the ATI site, and an FAQ suggested that the "ATI scheduler" needs to be loaded on startup. I put that in the startup folder, and it loads fine but I still the same problem with the recording, though. I am running Windows XP on a Pentium 4 1.6 GHz, 512 MB RAM, Asus P4B motherboard. Thanks!
