Whether it be done through an analog connection (eg. component) or digital connection (eg. HDMI/DVI/SDI), it all falls under the realm of the V4L subsystem, not DVB. V4L API's current facilities may not even extend far enough for such applications anyway .... I'm not certain, nor really qualified to comment (so someone with a more authoritative opinion should be listened to/consulted), but I expect that this would be rather pioneering with the current API and, hence, would require some additions/extensions to be made before such tasks could be realized. > There was a discussion over on the mythtv-users forum on HD capture > that devolved into another discussion, but there was an article on > converting your HD-DVDs to Blue-Ray > (http://howto.wired.com/wiki/Convert_Your_HD_DVDs_to_Blu-Ray).

If not, then in this thread ( http://www.gossamer-threads.com/lists/mythtv/users/223410#223410 ) you will see that Blackmagic reportedly expressed some openness towards the idea of Linux support. I haven't heard of anything further on the matter than that ... that doesn't mean that there hasn't been anything else said, and perhaps there is indeed some follow up ... I don't know ... but either way, that will require some searching, and that I leave as an exercise for someone else. - in regards to whether anyone around here has looked at this, I don't think any of the regulars ever have ... let alone ever considered it ... most people wouldn't even be aware of it (and the other existing alternatives ) ... in addition, it would be new territory, and likely a difficult development process ... so if there is anyone working on that device, or looking at it, its likely they are not directly associated or involved around here. - in addition to BM's Intensity and Intensity Pro, there are a few other "cheaper" solutions that are available. This thread on Doom9 (and despite its title) makes mention of them and provides examples of some of them in use: http://forum.doom9.org/showthread.php?p=1044824#post1044824 - as far as I know, the more expensive professional and prosumer solutions (i.e the AJA xena's, BM Decklinks, Accustreams, Bluefish444 cards etc etc) do have Linux support ... albeit, it is through proprietary SDKs or developed inhouse by the production studios using such products . There was a brief discussion about these on the V4L mailing list a few years ago; see/read through this thread: http://marc.info/?l=linux-video&m=115374256412690&w=2 - lastly, did that MythTV-users thread mention the forthcoming Hauppauge HD-PVR (component input) ? ... given that the LinuxTV developer rank does include a couple of guys from Hauppauge, and given that both of them have made mention of that device, and given Hauppauge's stance on Linux support is very positive, I'd be willing to bet that the chances of open/publicly available support for this device materializing are far, far greater than any of the other devices mentioned above.....though, bear in mind there are, of course, never any guarantees or certainties, nor am I speaking on the behave of anyone. _______________________________________________ linux-dvb mailing list linux-dvb@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
