Channel changing time?

[2010]

Hello All,

I'm new to nPVR (didn't really take any notice of it until the XBMC plugin) but impressed from my limited time using it, however my channel changing is quite slow in both the NPVR frontend & XBMC.

My setup comprises a TBS6981 sat card, Omnikey 3121 card reader and I'm using Oscam/Acamd (also tried Oscam/Hadu) and UK encrypted channels take approximately 6 seconds to clear, is this the best I can expect?

Thanks

It's hard to know when it comes to multidec and different card servers etcs. Do free to air channels change quickly for you? That'll be how quickly it has the potential to change channels, then any time on top of that is how long it's taking the multidec plugin to get the keys it needs, an then to decrypt the stream.

Have you tried NewCS cardserver? I'm using it and I have approx. 2.5 - 4 seconds channel change time for encrypted channels.

Thanks for the suggestion Reddwarf, I timed my channel changes and in NPVR (single seat) unencrypted channels are approx 2 seconds & encrypted HD are 4 (ish) seconds which means my Oscam/hadu is performing similar to your NewCS setup.

It seems my slower channel changes are actually with the XBMC client.

Yup, that's probably the fastest you'll get with a pc tuner anyway.

This is actually my main bugbear with my HTPC, I've used WMC/DVBLink, Mediaportal and now NPVR, each setup has been progressively faster but none are anywhere near the zap times TVHeadend achieves, which suggests that windows must be the underlying limitation?
