Well, I've been slacking on getting the next blog post out on the steps I used to build my DVR.  I will hopefully get time to post the next steps soon, but for now I just wanted to post an updated on my hardware setup.  Like I had posted earlier, I been wanting to increase the memory in the computer.  It started out with 512MB which was working fine, but I am sure the system would suffer if I was recording two shows and watching a recording.  I went ahead and added 1GB more of memory, giving me a total of 1.5GB.  I didn't do any specific benchmark testing, but the picture did seem to look a little better.  I really wanted this memory boost for when I add an HD tuner card to the system, which I hope to do in the next couple months.
     The other thing I added was another fan to the system.  I have been experience system lockups about every 2 to 3 weeks and I think it is because the system is overheating.  The box lives on the bottom shelf of a wood entertainment stand so I have a feeling the heat is building up in the enclosed space.  I hope this extra fan with resolve the issue.
     That's about it for now.  For those of you keeping track of the total investment so far that I have put into the system, the fan was $2.99 and the memory was $89.99.  I got both from Newegg.com and including shipping they came to $99.27.  Hopefully I'll have time to get the next few DVR steps up soon.
