Philips DVP642 problem with jumping to specific time

[pruss]

I fear I may be doing something dumb, but I cannot get my Philips DVP642 to jump to a specific time point. I press DISPLAY, use the down-arrow to get the "TIME ELAPSED", press the right-arrow to highlight the "00:00:00", but then any digits I enter give me the "hand" that means "operation blocked". I realize some DVDs block going to a specific time, but this is happening all the time--I am not sure I have ever succeeded in jumping to a specific time. Is there something simple I'm missing?

Thanks for any help!

In order to jump to the time make sure you enter 00 first if you want to skip within the first hour of video. (ex. enter 00 17 15 to jump to 17 minutes 15 seconds)
