Some people are using some kind of script that monitorizes 'dmesg' and restarts mythbackend as soon as the mt2060 read/write errors start to occur.<br><br>Also you could effectively try to upgrade your kernel, as it seems that the problem is closesly related to the USB layout. As a recommendation, you should also disable the DVB layout in kernel options and use lastest HG drivers from LinuxTV.
<br><br>I'm currently using Sabayon 3.3 (Gentoo) + 2.6.21-r3 + HG drivers with my Nova-T 500 and the disconnect problem is really sporadic (also I have EIT on, as I rely solely on it to retrieve program listings).<br>
