Who the hell would use mpeg2enc on a "whatever-pentium-w/o-mmx". What a processor would that be , a pentium 90 ? mpeg2enc is slow as hell even on Ghz machines , for what should it be used on such an old machine ? Anyway , the "alternatives" solution sounds reasonable to me (easy to make and usefull). -- Regards Steffen ____________________ counter.li.org : #296567. machine: 181800 vdr-box : 87 ____________________ Please dont CC me, since if I have replied I'll watch the tread.
