Hello, I tried to set my timeshift folder on a 1 GB ramdisk. Channel changing work's faster now(1-2 sec faster) but it produces a stuttering every 15-20 sec.
Has anyone experienced this problem, too ?
If i turn back to harddisk timeshifting everything works fine.

Anyone tried to use a SSD with mediaportal 1.0 ?

    Used a ramdisk once and it worked perfectly. Did not improve channel change, just like the devs mentioned it.
    Never tried a SSD. Way too expensive.

    Not quite a proper SSD, but I've been using a 4GB USB flash stick as a timeshift drive for a few months. Works really well. For some reason it did have occasional stuttering when formatted FAT32, but since I formatted it NTFS it's been completely stutter-free. A bit cheaper than a SSD :)

    Hi midasxxl,
    unless I'm missing something obvious, according to your system spec you only have 512mb of physical RAM installed in your machine.
    How can you assign 1gb to a ramdisk without the computer making a larger swapfile?


    Regards

    Hi,

    thats obvious wrong. I upgraded to 4GB recently, so i have now a Ramdisk with 2GB and installed the whole Mediaportal 1.0 RC1 and SQL SErver on this Ramdisk. It works very well, no stuttering with Mediaportal RC1 a nd channel change als improved to 2s.
    Also nrowsing inside folders improved much because i have thums folder on Ramdisk.
    I would suggest to integrate such a feature in Mediaportal, it would improve performance very much.

    Now I am confused - you started the thread with "Channel changing work's faster now(1-2 sec faster) but it produces a stuttering every 15-20 sec", but now you say:-

    It works very well, no stuttering with Mediaportal RC1 and channel change also improved to 2s.
    What has changed that you no longer have "stuttering every 15-20 sec" .... :confused:

    Hi,
    I changed from Media Portal 1.0 to Media Portal 1.0 RC1. Since then the stuttering is gone. I think that the ramdisk wasn't the problem becaus i had the stuttering also in my 720p movies. By the way the new powerdvd version works great with my new HD4550. It's really a great video card.

    I am using an SSD for timeshifting, specifically the OCZ Core SATA II / 30GB unit. Results are perfect. I tried using USB sticks with both FAT32 and NTFS but I always got occasional stuttering. On the other hand, I didn't try higher performance USB sticks. Probably it will turn out that certain combinations of USB sticks and/or USB controllers work and others don't.

    That's probably true - perhaps I've just been lucky with mine. The stick I'm using is a really cheap one (£5 for 4GB), not a high performance one. No stuttering at all since I formatted it NTFS. I don't watch any HD channels though, so I don't know how well it would cope with that.
