Arrgh! Not megapixels again! I swear, Dixons et al are responsible for this.
Megapixel refers to the size of the image. Thats it!
You can hack a mobilephone to take a 10megapixel shot I imagine, but it doesn't make it good! When you see a TV ad from Dixons, they'll go "This HP 5 megapixel camera is great!" or whatever.. the fact its 5MP doesn't make it great, the fact it probably has a decent lens and good manual control makes it "great" (it might suck

) if it can keep the image quality up at a higher MP count, then thats awesome because you can print the images off higher then. Remember, for print you prepare EVERYTHING at 300DPI generally, that means text/photos has to be very large or vectorised in order to print off at the same quality you get on a monitor (72DPI). My mobile phone takes 1MP shots, and it looks awful, because the tiny lens in it is rubbish and needs a lot of light or its next to useless. I don't even use it at its full potential because the photos it produces are simply better on a size lower.
So ignore megapixel count ENTIRELY when it comes to video, and only think of it as an after thought when it comes to still cams. Its not the size that counts, its how you use it :D :D :D
On another point: to hear a TRV900 operator say nice things about the HC1000 is so wrong! The VX2100 or PDX10 whilst being more expensive are much better choices in my opinion. The HC1k doesn't know which market its aiming at.. perhaps the "too much money, not enough sense" market?
