Your hard drive seems slow. Are you using ATA66 or ATA100 (80 wire
ribbon cable)?<br>
<br>
&nbsp;I using a cheap system I built this week. My system has an Athlon XP
1700,&nbsp; 512MB PC133 ram, 2 WinTV tuner cards, SBLive, Ensoniq, 60GB IBM
HD. <br>
<br>
hdparam -t returns:<br>
&nbsp;Timing buffered disk <a class="moz-txt-link-freetext" href="reads:&nbsp;">reads:&nbsp;</a> 64 MB in&nbsp; 1.65 seconds = 38.79 MB/sec
(same results multiple times)<br>
<br>
Top returns 44% idle time, with a load averages of 0.52.<br>

 style="font-size: 10pt; font-family: Arial;">I noticed that watching
live TV uses 95-100% CPU time using mpeg4 encoding at 640 X 480.&nbsp; My
system is an Athlon XP 1800 with 256M PC 2100 ram.&nbsp; Running hdparm
tells me that my hard drive throughput is about 23 Mb / sec.&nbsp; Is this
performance about what I should expect?&nbsp; If so, what would be the best
way to increase performance, more memory, faster processor or faster
hard drive?</span></font></p>
