I recently built a mythtv box using the PVR-250 and an nVidia GeForce FX5200. With the built in encoder in the 250 and the decoder in the graphics card, I only see the CPU (Athlon XP 1800+) use at about 1 - 2% while watching live tv, recording , or playing back. This type of setup would allow you to use a much slower CPU. I previously had a system setup (under windows XP with showshifter) using an ATI all in-wonder card and the picture quality and performance were terrible. The 250 is worth the money just for the picture quality in my opinion.<BR>

<PRE><FONT COLOR="#737373"><I>Hi all,
I'm about to assemble my MythTV box, and have a question about the capture
card. I searched the mailing lists' webpage, but couldn't find a specific
answer, just that upgrading would save CPU. I currently have an AverMedia
bt848 chipset card, and will be using an Athlon XP 2100+. Would there be
any substantial video gains from purchasing a PVR-250 to do hardware
encoding over the use of the AverMedia with software encoding? While not
bad, I'm not too impressed with the AverMedia's capture abilities thus far
(in a Windows environment, haven't moved it to the Linux box yet). I'm
pretty anal when it comes to video quality, so I want to do the best I
can.
Thanks,
Ben</PRE>
