<div><div></div><div class="h5"><br></div></div>Thanks Robert (and Raymond)! I did a brief scan of patch/diff from the 0.24 ticket for the HDHR lib update, and I see that a virtual channel tune function has been added. The 0.24 features list on the wiki just lists the lib sync--there is no mention yet that Prime capability will be included as a result. I've wondered how Prime would interface with the virtual channel map (assigning the familiar 3 or 4 digit channel number to a QAM transport/program slot), fearing that it might be behind a DRM wall. Will myth be issuing virtual channel tune requests, similar to how a STB is tuned? If that's true, then from an end user perspective, as long as my channel numbers are up-to-date from SchedulesDirect, using a Prime should be seemless, just like a STB, but without any anxiety over a flaky firewire connection. (Although personally, mine has been pretty solid connected to a Motorola 6200. I did have one issue upgrading my (Gentoo) kernel recently to 2.6.31 (from 2.6.19), with a memory allocation failure on some channel changes, but after a little research I believe that was a kernel firewire stack bug (old stack, not juju) memory leak. Upgrading again to 2.6.32 seems to have resolved it, but time will tell.) <br>
<br></blockquote><div><br></div><div> The Prime will tune by virtual channel, and will allow "fetch channels from listings source" as a means to avoid scanning at all. This is basically all that was necessary short term to make the Prime work. longer term (but still probably pre-.24) we spoke with the HDHR guys about offering a capabilities API to detect whether a given HDHR was CC-capable, and indeed whether that HDHR has a cablecard installed, so that we can activate or disable those UI functions as necessary. That's what we're still waiting on. But from a baseline *functional* level, the HDHR prime would work right now.</div>
<div><br></div><div>As far as how the channel changing will work, it will be basically transparent to the user (and indeed, to myth itself)... it'll just tell the HDHR "give me this channel" and the HDHR will stream it as ever. The only difference will be that on the HDHR Prime, the request will be for a logical channel number.</div>
<div><br></div><div>Anyhoo, should be fun regardless. We MythTV devs were wondering if the Silicondust guys would shortcut us to the front of the line for being such awesome people. ;)</div><div><br></div><div>Robert</div>
