Wow, pre2 is ancient, but I don't think that's the problem. BTW, pre7 is quiet ancient too, we've been wanting to release a new version for almost half a year now but have been waiting for server upgrade, I suggest CVS. But it doesn't matter for this purpose. You were probably right about the ratio thing, most likely the 'bitrate=32' I gave you is wrong, try 'bitrate=32.05', or lower/higher as necessary, until you get correct ratio... - ods15 ================================================================= To unsubscribe, send mail to [EMAIL PROTECTED] with the word "unsubscribe" in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]
