One thing I notice is that the audio lags during TV channel changing now I am on MP 1.1.0 (no plugins, no SVNs, defaults for most settings).
I did the un-install + manual clean of my old version (1.0.2) prior to install of MP 1.1.
All went smooth as butter.
However now when I change channel I get delayed sound. Interestingly it happens only on every other channel. I can count for about 20 seconds before the sound kicks in. Video works perfectly, perhaps a slight judder when the sound kicks in. If I ignore it and surf through a few channels the time shift gets mixed up. and it struggles to keep up.
I have the Timeshift file on the C: which is an SSD.
Never happened with 1.0.2.
Anyone else encountered this?
I might try moving the Timeshift to a HDD that is virtiually un-used.

    You mean just a one-time delay?

    I'm also having a lot of problems with 1.1, one of them is audio-sync. Although I'm not sure it's purely a syncing issue, because sometimes I get some "hickups" in the video as well.
    It happens always after a channel change, or switching between watching live tv and watching some recorded tv-show, and stopping the video and restarting seems to help most of the time (stop and play, no pause). see https://forum.team-mediaportal.com/bugreports-74/framedrops-after-channelswitch-analog-tuner-85154/

    Yes, thats it.
    Once the audio kicks in after say 20 seconds it is fine until I switch channel.

    :oops:

    Oddly enough it was just a simple drive space issue.
    Moved timeshift to a different drive.

    The cause is more interesting. I am running on a 32GB SSD, which now reports its size as 21GB. Been using it for about 1 year.
    I have another system with a brand new 40GB intel SSD. After 2 weeks of usage its size is now 37GB.
    Are these SSDs like a 2 year "candle" lifespan?
    I immediately applied all the tweaks I can find to reduce the writes on the drive. :confused:
