Hey people Im New Here And I Have A Question.

Ive Ripped Some Movies From A Site (Entire Video Clips And Movies)
But They Were All IN .ASF Format Then I Merged Them And Converted Them 2 .AVI But Then A Friend Of Mine Told Me That They Were Bad Quality (Although The Resollution And Screen Was Nice).
How Can I Fix This???
And Btw How Can I Disable Or Help The problem Of TMPGenc Illegal Floating Error??? Because Its Killing Me.

Thx And Cya
