I have Philips DVDR 615. When I set VPS/PDC on in a timer (which is supposed to ensure that recording starts when the program starts) sometimes it works, other times not. Sometimes it produces a popup that offers a choice: switch now / suspend / cancel. A. It seems odd to me that personal attention is needed, since the point of setting a timer is to automate the recording. B. Even if I give it personal attention and accept switch now, the popup just repeats itself. Any suggestions on why I'm having this problem?
