Hello All I'm new to the forum having just purchased PTE 7 and Roxio Creator 12. I have a lot to learn about both programmes but so far so good. However I'm a bit confused as to which video codec to use when creating an AVI video file which would be compatible with Roxio. I have searched the forum and from a very old post from 2006 I found this: 'The one which you should use is Microsoft MPEG 4. If you don't have this one listed, then you should download and install the free ACE Mega CodecS Pro pack here:' When I create an AVI file I have the following video codec options available within PTE: DVIX 6.9 YV12 decoder Microsoft RLE Intel IYUV Cinepac by Radius PTE video codec. DVI 6.9 2 [Logical CPU's Full frame Decompressed My question is really, are the above codecs ok, which one should I be using, and if I need alternatives where can I get them. Many thanks. Kind regards. Neil
