1 GHz fast enough for realtime MPEG2 (Leadtek 2000 expert)?

[DaveSimmons]

I'm putting together a HTPC box and already have a tualatin celeron 1.0 and motherboard on hand. Has anyone used something so "low powered" for recording using MPEG2 mode and the Leadtek TV cards?

I don't need the fancy features like simultaneous play and record, just one at a time.

I?ve read IIRC the requirements for MPEG2 are about in the 700 - 800MHz P3 range so you should be fine with that Cel-T 1.0. It?s basically a P3 on a 100fsb.

You could always run that Cel-T 1.0 at 1.33GHz if you needed some extra juice.

1GHz should be fine for on the fly MPEG2 encoding,..

Let me also quantify that I am using a 450MHz machine to try to do live encoding and it drops a few frames and sometimes gets choppy but it does sorta work so I'm going to guess that you more than double this and you'll be fine.

Software I used has a minimum of 800MHz, obviously I'm getting away with a little less..

You should be okay with a 1.0 Tualatin, but the P4 Celerons are extremly slow for the clock speeds they run at.

I could not do software MPEG-2 encoding on a 900 MHz TBird, but I think I was JUST below the minimum requirement. A 1.2 GHz Duron/Athlon/PIII would be my minimum recommendation. You should give your machine some headroom so that it does not choke as soon as you move the mouse or some random system task executes.
