At the moment, all the DSLR camera cannot record video clips.
For long term use, a DSLR is good as it can have more option and assessory for photo taking. Wide range of Lens can be selected (remember that Canon EOS 400D use APS-S side CMOS optical unit. It would have a 1.6X magnification for the attached lens.)
For EOS 1D series and 5D series, they use the Full Size CMOS so the choice of lens is much wider.
For a CANON PowerShot G7, it is good for travel and more convenience for a starter or casual user. It has 10.0 M Pixel and also have the manual setting function.
For more, you may also equip the Wide Angle Converter (WC-DC58B) and Tele Converter (TC-DC58C) to make it with wider shoot range.
The wide angle converter has 0.75x and can widen the lens to ~26mm.
The tele angle converter has 2.0x and can lengthen the lens to ~420mm.
Both cost $960 at the Canon shop. It may be cheaper for buying it at other shop. However, a adaptor (LA-DC58N) must be equiped for the attachment of the above lens. It cost $260 at Canon Shop too.
For more details, you shall visit the Canon Show Room in TST. You can try all the camera first and select the one most suitable for your need.
For a DVD Camcorder or DV Camcorder, it is just up to how frequency you need to take video. There are so many format in the market at the momont. DVD, mini DV, DV, Harddisk etc. I do believe the Harddisk type would be the one for the future. More convenence to edit and storage in computer. DVD format is ease to use and can be edited immeditate and playback on general DVD player. For DV Tape & mini DV Tape, it should be no longer use in the coming future as the technology is changing date bu date...!
At the end, the photo quality of a DSLR camera would generally be better than a Compact DC as the size of the optical unit is different.
