Quick question for you guys.
What's better to conserve battery power...watching a movie via mp4 on my Hard drive or watching a DVD via the disk drive or watching a DVD ripped to my Hard drive? Seems like I get more hours via the Dvd?? Has anyone else found this? |

HD. It spins much more easily, and it has to be on most of the time, anyway.

as ghoti said, watching from HD much more efficient.

Or, you could buy a card reader and a compact Flash memory card. They have mini-hard drive versions that go up to 8gb I think. That will REALLY save power.

That's an awesome idea about the card reader.
Anyone else try this w/a 4 gb flash card? |

I don't think the card reader would save enough battery power to compensate for the insane price you'd have to pay for a 4 to 8 gb card. I think windowsrookie was half kidding anyway.
You'd be fine using your HD. |

In order to save power with USB, the hard drive would have to be idle. (not spinning) Otherwise you are using a hard drive and USB.
Between formats, a MPEG2 file uses less compression and therefore less processor power to play back. MP4 files save lots of space but use more CPU power. I would use MPEG2 to bet the most of your battery life. This doesn't matter much on the latest laptops, but I can squeeze about 20-30 minutes extra from my 400Mhz Pismo. |
