    DVD IQ varies by device

    I am having problems with a DVD I just burned.  Depending on the device I play the DVD on, the image quality varies quite noticably.  My 50" TV actually presents the sharpest representations while my work laptop is fairly "soft", with the home laptop decent but not as good as the TV.  I am an avid photographer with solid technique and the DVD consists of the best 10% or so of pictures I took on an amazing trip.  So the IQ of the photos themselves is great.

    The specs on the various hardware involved are as follows:

    Home PC (used to burn the DVD):
    Dell Dimension 9200 Core 2 6600 2.4GHz, 3GB RAM
    Radeon X1300/X1550 Series (I believe it is 256MB dedicated memory)
    XP Pro SP3
    Using Pinnacle Studio Plus version
    Selections within the Make tab where disc type of DVD and Video Quality for the burn was Best Quality
    JPGs used in producing the DVD ranged in size from 1.8MB to 14.5MB


    Devices the DVD was played on:

    Home TV:
    Panasonic TH-50PX60U
    50" Plasma 780P TV, using an DVD player capable of upsampling for HD

    Home laptop:
    Compaq Presario CQ50-210US Athlon Dual Core QL-62 2.0GHz, 2GB RAM
    NVIDIA GeForce 8200M G (shared memory; don't know how much)
    Windows Vista Home Premium SP1
    Can't recall the DVD player used (and I don't have access to the laptop at the moment)

    Work laptop:
    Lenovo T400 core 2 duo P8400 @ 2.26GHz, 2GB RAM
    ATI Mobility Radeon HD 3400 Series (I believe it is 128MB shared memory)
    XP Pro SP3
    Used InterVideo WinDVD 5 to play


    My questions:

    1. What is causing my image quality problem?  Is it the size of the JPGs used?  The video cards on the laptops?  The upsampling of the DVD used with the TV is giving the TV an unfair advantage over the laptops' DVD devices?  ???
    2. What is the optimal JPG file size to optimize IQ?
    3. Any other suggestions for maximizing IQ?

    I am going to slip another quick question in here.  I hope that's OK.  I was looking for a way to change the menu button frame colour from white to something else (black in this case).  Is there a way to do that, or am I out of luck?
