Starting the Live TV (if not running) takes approx. 30s. This is with the latest TV Engine v3 (TVEngine3 Snapshot: 05-31-2007 01-22h Revision 14765).

When looking at the logs, you see an awful amount of
Code:
31-05-2007 20:41:41 [c18]vmr9:InitializeDevice() 720x576 AR 720:576 flags:24 buffers:1  fmt:(3231564e) NV12

31-05-2007 20:41:42 [c18]vmr9:DeleteSurfaces()
lines in the vmr9.log file whenever the vmr9 renderer is initialized. It amounts to almost 20 seconds of the 30 second lag time. But once the live tv is running, changing channels are more normal, about 2-3 seconds. See analog_log.zip for the logfiles.

But, if I watch DVB-T channels instead of analog, you get a the 30 second pause for EVERY channel change, making it 30 seconds per change. See digital_log.zip

What's even worse is that recorded material has the same delay. Even with the TV off, the delay is present when trying to view recorded material.

I've tried enabling/disabling the FFDshow filter which I use to enhance the picture quality but it makes no difference, the lag time is the same.

I've also fiddled with the options for vmr9 (exclusive enabled/disabled) but it made no difference (except for tearing issues ;))

What video codec are you using? I had this exact problem with the dscaler codec, but changing to PureVideo solved the 30-sec delay for me.

Unfortunately I now have worse deinterlacing and combing artifacts that I didn't have using dscaler...

Can't have everything I guess!

Have you been able to figure out the issue? I have the same slow first startup with analog.

    Same thing happening on one of my htpc's that runs in single seat configuration. Takes forever to start watching tv, so bad that i'm considering to switch back to the old tv engine.

    I'm experiencing exactly the same thing on a single seat setup. Anybody had any luck solving this? Is it db related or is it the transmission of epg and channel data between server and client each time you enter the My Tv?

    kind regards
    Martin

    I'd like to add that I'm having this problem too on the first start up of My TV or going into recordings. It takes about 30 seconds as well the first time. I'm using FFDSHOW for both video and audio.
