[streaming] Re: WebCAM Device Recommendations

[Chen Li-Shien]

QuickCam Pro 3000 and Philip ToUcam use the same chip

so I have questions about the following discuss with these two cameras 

1.The Phillips camera also works well means Philip ToUcam also works well 
  with vls ? 

2.Since QuickCam Pro 3000 and Philip ToUcam use the same chip, 
  QuickCam Pro 3000 also works well with vls ?
  (but the following said that quickcam camera segv's with vls)

I dont know if I should buy "QuickCam Pro 3000" or not to test vls
my country only sells QuickCam Pro 3000 , so I need to ask everyone's idea

thank you
