There seems to be a small mix-up with .wma audio. When you choose WMA codec v7 (wma1) it converts into WMA codec v8 (wma2) and vice versa.

Be careful installing the newest version 3.0.4.6.
Norton Security had an alert: one of the integrated DLLs (libfaad.dll) is containing malware (Suspicious.Cloud.7.F)
You should check by your virus-scan before installing - maybe, it is only a FALSE alert.

well,"xmedia recode" overall it is a good choice but how about using/comparing it with some other best converters/encoders (Although my prefferred ones are handbrake & xmedia recode because of availability h264 options)

1-handbrake (freeware)
2-format factory (freeware)
3-mediavatar(better conversation speed/quality than the followed affiliate ones)/imtoo/xilisoft) - some other choice of the same category is aimersoft-4videosoft(shareware(s))
4-super (freeware)
5-staxrip (freeware)
6-dvdfab (shareware)
7-total video converter (shareware/freeware)
8-pepsky all in one (shareware)
9-quick media converter (freeware)
10-iWisoft Free Video Converter (freeware)

for a full pack converter/encoder , choose mediacoder but it has a heavy GUI which makes it a-no-choice for many users .

for video fixing(avi/divx/rm(vb)/wmv/asf) , choose video-fixer (A discontinued shareware project but you will be able to find registered one around the internet)
