ludayodaYes, to make it cleanly install, you must have at least 1024MB free (you can have more and it will only use what it needs) AND only have a single partition ( C: ) on the disk. Then, I suggest you install WinXP Pro and next install the QP2 CD. Then you can go ahead and install any drivers, etc.. Oh, and don't forget the QP2 Windows code (39Mb d/l listed somewhere above) that allows you to use QP2 while within WinXP.

If you have QP1.x then forget it, it will not play any DVD files from disk, ever.
If you have QP2.x it seems your only hope is to convert the VOB into an xxx.MPG file and play the video, since it will not play the VOB's directly. Sidenote - After using an old copy of "daemontools" to mount a networked ISO file of a DVD as a new drive ( G: ), when I used QP2/Windows it started playing.

Too bad there is no network code in QP2/Direct.
misc.. just for the record and any future hacks
In my continuing quest to figure out what the heck they are doing within the QP code, I have made some trivial progress. Here is what I've done thus far, with GHOST backups along the way -
1) Installed WinXP on a 4GB partition, with minimal HP h/w drivers (Lan, Vid)
2) Installed QP1.2.32, by booting from CD included with Notebook.
3) Installed QP2.0.2413 from downloaded CD
- First had to add register key - HKLM/Software/QPFlag QPFlag=0x03
4) Installed QP2.0.2412 (yes, 2412) Windows code, downloaded from above.
5) Installed Quick Launch Buttons (QLB) 5.2 (look under DV2000t d/l's) which can point to QP/Windows.
Since I was looking at Master Boot Records (MBR), it seems that QP1.x does not alter the MBR. This implies that the bios has code already embedded to look for something on the disk indicating a QP1 partition.
QP2.0, on the other hand, modifies the MBR and 'appears' to jump to some mysterious code in the 07A0 segment. Current hypothesis is that it is reusing some bios code ala QP1.x, but given my rusty asm skills who knows?

So, now I have a machine with QP1 and QP2 loaded. Starts up like this:
Power Key -> WinXP
Music Key -> QP1.x
DVD Keay -> QP1.x
Power Key - Music Key -> QP2.0
Power Key - DVD Key -> QP2.0
The direct access to QP2.0 does not work everytime and I'm not sure when or why, yet.
