MPEG2 files of VOB2MPG not accepted by ATI AVIVO video converter

[33M344]

Hi,

I used VOB2MPG to get single MPG files from TV series DVDs and want to convert them to h.264 by using ATI Video Converter with Stream technology.
Unfortunately these MPG files are not accepted by the encoder:


"The selected source file contains either an unsupported video/audio format or no video/audio content."

Then I wrote to ATI support and received that MPEG1, MPEG2, Video CD, Super Video CD, DVD, MPEG4 (DivX compatible), WMV9, Portable Media Center, H.264 (AVI), MPEG4 (for Sony PSP) and H.264 (MP4, for Apple iPod) are supported.

Does anybody have an idea?

Thanks in advance!

Okay, AVIVO under XP 32-Bit accepts the file, whereas Windows 7 64-Bit does not.
