Blotches in Mpeg Clips

[hfsaidi]

When I convert a certain DVD movie to Mpeg 1 format and then edit that Mpeg, I sometimes get pixelated blocks/blotches. This often happens when I try to join two (or more) Mpeg clips together.

Could someone please help?

Cheers in advance,

you should probably tell us more about what programs you are using...

Ok, here's the scenario ... I use 'Super DVD Ripper 1.89' for converting from DVD to Mpeg1 format and the Mpeg Clip remains perfectly alright upto this stage. It is only when I join the edited clips together in 'Sonic Foundary Vegas 4.0' (which is ofcourse a fairly decent piece of software) when in some places, where the two clips have joined, the blotches appear. Ok, another software that also comes into play (between the conversion from Super DVD Ripper to Vegas 4.0) is 'VCD Cutter v4.04' for extracting the desired clips which would then be imported into Vegas 4.0 for the final editing.

Hope this gives the exact picture
