Hi all,

I'm sorry, but I too am getting this:

OS :: Required: Windows(R) :: Found: Win XP [PROBLEM]

"OS" Problem causes all kind of errors with most output containers/codecs
Could be due to a slow PC, very low available RAM or require Rebooting.

It happened after I applied SP3 to XP.

If I ignore the warning, then some files will convert, but others will not.

This MAY be a seperate problem however - I click on the files to to get the codec details and the ones that will not convert say this:

I also updated Windows Media Player at the same time, but cannot think why WMV2 will convert, while WMV3 won't. I have tried checking and unchecking Direct Show decode, but it makes no difference.

I would be most grateful for any help - The computer is a Dell Inspiron 9100, 3GHZ Intel, 3GB RAM (SUPER only reports 2GB, but the full 3GB is there and working) with 34GB free on c: drive
