Okay. I must admit that I'm starting to fall in love with my XBMC, but I'm still trying to perfect it!

It could be that I'm using a laptop with ServerWMC, connected wirelessly to my router, even though XBMC on my RPi is wired... but, is there any way to speed up the loading time for live TV (and recordings)? To load a channel, or recorded TV, it takes about 20 seconds. (It also takes a long time to load USTV VoD, and any channel I choose within.) Loading a channel or recording on WMC on my laptop takes about 3 seconds.

Don't get me wrong, if I have to wait 20 seconds for everything to load, I can live with it. It is still much less expensive than DirecTV!

Thanks for any help you can provide.

I'm using a laptop with ServerWMC, connected wirelessly to my router,

There you go.

I don't understand why this log shows that you are still remuxing all recordings, per your other thread I thought you turned this off. Certainly the playback of recordings will start slower with this on.

Are you saying that the pi (wired) is much faster than the laptop (wireless)? Or that both are way slow? Once you turn off the remuxing of recordings, a recorded file on your laptop should start immediately, or at least as fast as your network connection allows. Even for a live TV stream, 20s is way slow, so something is wrong somewhere.

But the simple answer to your question is we have made the live startup as fast as we can get it without a major change in architecture. Although you can get faster live-TV start times by using the Margo build of xbmc on windows platforms.

Thanks for your response. I'm sorry, I'm still kind of new at this... In your response to my other thread, you had told me "Debug_RemuxAllRecordings set to true" was not needed. So I unchecked that item. I didn't realize I should also uncheck Recordings_Remux active recordings, but I will try that also and let you know results.

To clarify, I was saying that the pi (wired) is much slower then the laptop (wireless). However, the wireless laptop is controlling the tuner, WMC, and ServerWMC (and storing the recordings).

You are right, you should have remux active recordings turned on (true), but in the log you put up yesterday remux all recordings is true. Its probably showing this because you didn't restart swmc, so I'm sure its fine.

If you can, you should try some experiments with your laptop (server) using a wired connection and test the performance diff.

Okay, I spent most of my sleepless hours last night thinking about an old Vista computer I could convert to a backend PVR, so I would avoid the lag when choosing a channel or recoding. This morning, after seeing your response, I switched my laptop to a wired connection, changed all of the IP addresses in XBMC and SWMC, and restarted both.

Unfortunately, there is still a 20 second delay in all Live TV channel and recording selection plays. At least I now know it isn't because my laptop was connected wirelessly! Do you have any other suggestions I could try?

Thanks so much!

If you look at this last log you posted serverwmc is taking from 2.7s to 4.2s to start the live stream, which is about average, so the delay is not there. Frankly I have never used a pi to start a live stream so I don't know how long it takes running xbmc to get it going. Can anyone else comment?

Might be worth trying a "newclock4" test build for the PI. OpenELEC or raspbmc versions are available.

This has the "fast channel change" patch which may help with your issue.

Note: these are Helix (nightly) test builds. You may have compatibility issues with add-ons that haven't been updated for Helix, so make a backup first (or use a spare sdcard).

Thanks for you response. I will try this in a couple of days, when I get another sdcard and will let you know results.

Hello,

I have almost the same problem.
With the testbuild from 15.08.2014 openelec livetv und recorded view all fast and stable.
But with all testbuild within newclock4 it do a long time 20s to see a view and is full of stuttered.

How can I actived/deactived "fast channel change", so that I can test and find my problem?

No issues for me, I do this regularly and it doesn't seem to take much longer (it is likely +1 second or so) than starting one on the same client that has SWMC on it.

Wireless is not reliable for stuff like ServerWMC. You need the machine running ServerWMC to be wired. Otherwise, you just like hurting yourself, it seems.

You may have missed the part where I said I tried it with my laptop wired, unfortunately, with the same result.

So, for curiosity sake, could you tell me if you are running Raspbmc, and what version of XBMC on your RPi? Do you have any special settings I could emulate? Just to confirm, you are running SWMC on a PC/laptop?

Thanks!

Sorry for the delay, watching too much RPi Live Tv..
I am just running the standard non nightly RaspBMC, Gotham.
I have mine setup as a USB flash drive install clocked at ~1Ghz, wired connection, no special settings.
SWMC is on a networked 1GBps main computer, nothing too new, AMD A8 something, something, Pci-e tuner cards OTA.

Thanks for the information. Maybe I need to set up a USB flash drive install and see if that makes the difference!
