I am having problem in live recording from our JVC GY HD111 in HDV Format on my Vostro 1014 with following config:

Core 2 Duo 2.10GHz, 2GB RAM 400MHz (DDR2 800), 320HDD Samsung HM321H1 ATA, Win 7 Ultimate 64Bit, Graphics: Mobile Intel GMA 4500MHD -> 814 Total available graphics memory, 64MB Dedicated Video Memory

I have installed ffdshow only, In Vegas Pro and HDVsplit it is giving output in m2t file and Adobe CS 5, its giving mpg2 but in both cases the video has got very disturbing blinking lines... see this video

Where as on my assembled Desktop, everything is working fine.. except Vegas Pro 10 is not detecting the device in HDV mode but CS 5 is doing great job !!
My Desktop has 4GB RAM, and Intel HD graphics 64MB Dedicated and i5 3.33GHz

So plz suggest me. what can be the cause for this....
