:-) I know that...I misphrased my sentence... What I was saying is- how can data stored on a 700mb cd become almost 800mb when an image of it is stored on harddisk! Anyway, you have already answered my question in the following paragraph... Thanks so much! :-) > > Why should this increase the size?

Got errors like these: ----------------------------------------------------------------------- Too many audio packets in the buffer: (3681 in 8388999 bytes). Maybe you are playing a non-interleaved stream/file or the codec failed? For AVI files, try to force non-interleaved mode with the -ni option. ----------------------------------------------------------------------- And finally, there was this message: ----------------------------------------------------------------------- A: 1.1 V: 0.0 A-V: 1.093 ct: 0.003 1/ 1 0% 0% 0.0% 0 0 0% Successfully enabled DPMS alsa-uninit: pcm closed Exiting... (End of file) ----------------------------------------------------------------------- Anyway..thanks a lot for spending your time to help me out... I'll see how vcdgear can help me... time to explore! :-) -- "The Power to Imagine, is The Power to Create!" -TTux -- ______________________________________________________________________ Pune GNU/Linux Users Group Mailing List: ([EMAIL PROTECTED]) List Information: http://plug.org.in/mailing-list/listinfo/plug-mail Send 'help' to [EMAIL PROTECTED] for mailing instructions.
