I always had the (possibly ill-informed) impression that it was also<br>
quite dependent on the type of tuner you had and the quality of the<br>
driver for it. e.g. I wouldn't be surprised if a network based tuner<br>
took a little longer to talk to and to begin streaming the new channel<br>
than the onboard tuner on some dedicated h/w PVR. Likewise I'm sure<br>
that the quality of PCI and USB tuners and their respective drivers<br>
varies greatly wrt tuning times independently of any issue myth itself<br>
might have. Whereas the h/w and drivers are something that h/w PVR<br>
manufacturers may or may not have optimised (and I expect some are much<br>
better than others). Plus with a PVR they are only supporting one<br>
specific combination of hardware and an integrated driver+application<br>
stack (quirks and all) whereas a myth system can host a wide variety of<br>
different tuner hardware, all with different quirks.<br>
<br>
So even if there was someone willing to try and contribute to a<br>
seamless live tv experience, it would very likely need to be a full<br>
stack effort (so drivers as well as myth) targeting a particular subset<br>
of tuners (of course some subset would be generic, but by no means<br>
all). For it to be seamless across a wide range of tuner stacks you'd<br>
need a wide range of people willing to contribute such things...<br>
<br>
Annecdata: My parent's Humax (I think?) PVR seemed to me to be fairly<br>
clunky for channel surfing, worse than our merely slightly clunky<br>
MythTV live experience (which is rarely used for live tv though).<br>
<br>
(rereading the quoted stuff above I'm not sure now I've picked the<br>
right place in the thread to make this comment, oh well)<br>

Thanks for the insights Ian. I think you're right.<br>
<br>
By supporting a wide variety of hardware it makes sense that there's less optimisations of a particular card, it's firmware and drivers.<br>
<br>
I wish there was a recommended hardware list, because ideally I'd buy the same tuner a developer users!<br>
There's not a lot of choice in tuners for some countries though...<br>
<br>
<br>
This conversation started as I had naively hoped that by putting a new system together with a newer tuner that it could change channel faster.<br>
<br>
For reference my old system has two PCI "Technisat SkyStar2" DVB cards while my new one has a "DVBSky T982" PCIe card. <a href="https://linuxtv.org/wiki/index.php/DVBSky_T982" rel="noreferrer" target="_blank">https://linuxtv.org/wiki/index<wbr>.php/DVBSky_T982</a> It's using the OpenELEC firmware.<br>
<br>
I spent some time researching DVB-T PCIe based cards and there wasn't a lot of choice. As it is I had to buy the T982 directly from DVBSky in China via email and Paypal!<div class="HOEnZb"><div class="h5"><br>
