My front-end can't support HD playback, and my TV can't display it. But I like the aspect ratio and extra channels (eg. 5 subchannels on PBS) of ATSC. > your best option for "live" transcoding from ATSC -> NTSC is plugging > the S-Video/Composite out of your cable box into a PVR-x50.

That's an approach I hadn't considered. So for OTA use, I could get something like this standalone ATSC receiver, set it for 480i output, feed that into a PVR-250 through the s-video input, and use MythTV as usual including pause etc. Interesting. I had a mental block on that, but seems obvious once you suggest it. > Put another way, if your machine can't do playback (=decoding) of > high-def streams in real time, there's no possible way it could do > transcoding (=decoding + encoding) of high-def streams anywhere near > real time. Well, yes. I guess I imagined doing the realtime transcode on a backend machine, not the frontend which is highly incapable. :) Thanks, glen _______________________________________________ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
