    HTPC/server

    I know there are many HTPC threads already, but it probably wont hurt to post one more. I currently have a Ubuntu based server (mostly working as a file server via nfs) running on old Athlon 64, which is starting to wear down. I'm planning on building a new setup, which could serve as a server and HTPC. It should be quiet and be able to play 1080p video.

    Sandy bridge seems attractive, because it packs a lot of power and runs cool. I have learned about some problems, however. Firstly, the first H67/P67 chipsets had some SATA problem, right? But the new P8 ones should have this fixed? Another problem, as I understand, is the integrated graphics of SB. If I plan to use external nVidia card, will there be any issues in playing back video (on CPU with mplayer-mt, I still won't fully count on VDPAU)?

    My current "shopping chart" includes these:

    Intel Core i3 2100
    Asus P8H61 B3 Intel H61 LGA1155
    Kingston Valueram 4GB 1333MHz DDR3
    Asus ENGT520 SILENT/DI/1GD3(LP) GeForce GT520 1024 MB DDR3
    Corsair CX430W
    Antec Three Hundred

    plus my old hard drives and what not. I feel that I should go with the standard casing, since I have a place for it in my living room. Those HTPC casings seem a bit overpriced. Also I wan't to have room for extra HD:s. Will there be any problems with running the Lucid with SB? I would prefer LTS version.

    I can play xbmc on natty w/ vdpau ok using the maverick ppa... but it does sound like an xbmc bug. Maybe check out their forums for any similar issues or ask around.

    I tried mplayer2 and both multithreaded playback and vdpau result in smooth playback of full hd video. Nice.
    I also tried to update the nv driver via ppa but this did not improve xbmc playback. Actually, it seems that not only
    full hd video but also low definition videos suffer a great deal of jitter when played back in xbmc. I did install this
    from maverick repository, since official ppa does not yet exist for nutty narwhal, so maybe this is a bug in xbmc.

    There's a PPA here:

    https://launchpad.net/~ubuntu-x-swat/+archive/x-updates

    Enable xbmc debugging then check the log file for errors.

    Do you have any problems playing in mplayer2, etc.?

    I meant to say 270.41.06.

    By pressing 'o' the info says "dc:ff-h264_vdpau-vdpau" and cpu percentages are below 5. Quick google on 280.13
    gave that some people get system hangs. What is the best way to install the latest nv driver nowdays?

    BTW I'm running Ubuntu 11.04.

    I finally got the HTPC built of the following components

    Intel DH67CLB3 board
    Intel core i3 2100
    nVidia GT520
    4 Gb DDR3 1333

    I ran some videos on xbmc with vdpau enabled. The 720p ones ran ok but 1080p was practically unwatchable.
    I used the restricted nvidia driver 170.41.06.

    When I run the same video on my desktop with GTX260 and driver 280.13 the playback is smooth. Of cource
    this is a lot more powerful card, but I thought the vdpau on GT520 should be capable of pushing 1080p.

    I went through this whole process with my new MythTV backend and my final conclusion was that it would spend most of the time idle where the power consumption was very low anyway, so I went with the i5-2400 instead of the 2300S low-power version that was 20% slower and $20 more.

    That said, the i5 is probably overkill because I rarely see more than two cores maxed out when recording (transcoding broadcast HD to H264).

    I almost forgot, that I should check whether the integrated sound chips of common 1155 mobos
    work under Ubuntu. Asus P8H61 B3 has ALC 887. Any problems here?

    I was also considering, if I should buy only slightly more expensive DH67CLB3 with sata III support. However, this MB uses ALC 892 sound chip, and google results on this imply problems.
