Hi guys,

Something I have noticed for for the last few issues of MP (actually since I can remember), I have MePo configured to launch live full screen TV (single seat setup), but there is a pause/hang for 4 - 5 seconds before it is first displayed (this manifests itself as a blank blue screen when using Blue3Wide). I appreciate the graph has to be initially build, but I'm wondering what is causing such a delay?

The TV log states DoSetChannelStates takes 4 - 5 seconds, so I think it is this?

2010-11-23 19:47:19.213134 [Channel state thread(28)]: ChannelStates.DoSetChannelStates took 5572 msec

I use a channel group which contains just the specific channels I watch (ie I only watch ~130 channels out of a possible 800), I believe the DoSetChannelStates is processing all the channels hence the delay. But what is it doing? Is it possible to speed things up/not do what ever it is doing (without deleting all the extra channels I don't watch?)?

Thanks,

J.

If you delete channels that you are not actually using this can speed some things up quite a bit. You can order your channels by group and from there you should be able to highlight all the ones that don't have a group and delete them

Edit: Read the whole post

(without deleting all the extra channels I don't watch?)?

Is your card set to pre-load?

also post logs as this does not sound like it is starting the graph that is taking the time

Hi there,

Apologises for not getting back sooner, I tried to capture some logs from my test machine (but this only has one card and is running MS SQL) - its not showing this issue.

I couldn't initially post my logs from my main machine as I was running some naughty software (didn't want I.L. shouting at me). So I've quickly removed MePo (and associated naughty software) and performed a fresh install with 1.2.0). I have been experiencing this issue with versions before 1.2.0 (hence why I haven't put it in that forum)

My cards (two off) are set to preload, pause graph, type DVBS, grab EPG. All my channels are enabled and mapped to both cards. I am running My SQL. I use groups within MePo to control what channels I want to see)

I performed three tests (not sure if they will help or be relevant). The test was simply to click on TV (with MePo already running) (Its configured to run full screen live TV). First test is with a group with just 2 channels in it, then another test with a group containing 100+, then finally with all channels. I was wondering if this affected the speed.

I appreciated I could simply delete the channels I don't use - assuming its linked to the number of channels - but it makes rescans awkward.

Many thanks,

J.
