I recently replaced my PC with a new HP e9150t running Vista Home Premium
64-bit. I have a Canon HV20 video camera and have been recording HDV on it
for over a year. My old PC was an HP Pavillion a1560n running Vista Ultimate
32-bit and I am satisfied with using Windows Movie Maker for HD video editing
with my camera, aside from a crash now and then.

On the new PC, the video being imported is choppy at times with an
occasional few horribly distorted frames. This seems to be related to the
HDV import because I can use Movie Maker to publish my existing projects in
WMV-HD. These distortions appear during the preview during import and
persist throughout the editing and publishing process.

One of the main reasons I bought this new PC was to improve my HD video
editing experience. This is an i7 920 with an ATI Radeon 4850 1 GB video
card and 6 GB of DDR3 RAM. I'll be happy to share any other information
about my setup.

Does anyone know how to resolve this? Please help...
