Ok, so here's a basic rundown, I was previously having some IOBOUND errors with R5E50. I had increased the mpg buffers to about 64mb or so each, and that seemed to resolve the issue. My motherboard is an Asus A8N5X with an X2 3800 (s939) processor and 1gb of RAM.

I've reinstalled with R5F1 (from scratch onto a brand new HD, this was not an upgrade from R5E50). I'm finding that I still am having the same problem.... but my understanding is that this newest version of IVTV does not offer me the option to increase my buffers. If I'm recording and mythfilldatabase runs I will get overflowed buffers. If I'm archiving to a DVD and recording I will get overflowed buffers.

lspci -v shows a PCI latency of 0 for my IDE controllers, which I think ultimately is my problem, bumping the buffers up was simply a band-aid that resolved/lessened the impact of this situation.

Is there a mobo that someone would recommend for me? I'd like to keep my socket 939 processor and use my exisitng 1gb of ram (2 X 512). I'm running the following hardware:

Asus A8N5X
2 X 512 MB Ram
s939 3800 X2
320gb Seagate IDE HD
2 X PVR 150 (one MCE one non-MCE)
Generic IDE DVD burner
Nvidia based PCI-X video card (can't recall exact model)
onboard sound & LAN


I'd like to keep my costs down as I resolve this issue, so swapping just the mobo and reusing all other components is ideal for me. I'm looking for firsthand recommendations, if you have a motherboard (and similar equipment in it) and are able to do the things I'm not able to do, I'd be interested to hear what you are using. When you run 'lspci -v' do you get a latency reading for your IDE controller?

Here is the link to the page that discusses the PCI latency issues.

Oh yeah, I'm also totally open to fixing this on the existing hardware if anyone has any thoughts or has tackled this already. Though I'm doubting that.

=)

Thanks in advance.

As I've poked around on the forums here, and researched elsewhere online, i think I may have come upon my solution.

I think the board for me is the Asus A8N-VM CSM.

Has anyone run into IOBOUND errors with this as their platform? Is the support for this solid and top notch now? There are posts from last year of people having some issues with it.... but there's been a few releases since then and I"m thinking that this is now a pretty solid choice.

Thoughts?

What about the MSI K8N? I believe that is used in the Dragon 1.1 platform. I use a ECS KN1 Lite mobo with my socket 939 setup. Socket 939 motherboards are starting to faze out....

My Asus A8N-VM CSM is great, no problem watching/recording/commercial flagging or transcoding simultaneously. I've never noticed that mythfilldatabase caused any problems. I have 512MiB RAM and I end up using swap over time which slows down the system. With 1GB you should be good to go even using mythArchive which on my system gets me 4-500MB into swap.

Whether you will be able to find one of these or not is a question though, haven't seen one on newegg in many months. If you do buy this MB, go find the SPDIF and S-Video dongle cables (if you need them of course). I bought both up front as I needed S-Video right away, and thought I might use SPDIF someday (not yet).

Oh and I only use SD, no idea how well it would perform with HD.

I'll be using SD only as well, so no worries there. The output bracket isn't an issue for me, this machine is a dedicated backend. I do all my viewing either on one of 2 xboxes or an Athlon XP 2400+ frontend system.

Thank you for the reply, I do think it may be a bit of a challenge to find one.... but knowing what I"m looking for is the first step.

Lucky me, looks like my cousin has this mobo and is willing to trade me for one of my other S939 boards that is generating the IOBOUND errors.

I'm in good shape it would seem!
