I have a 6200 STB from Comcast in the Philly area, and I'm in the midst of setting up a system using firewire - this is what I've observed so far. I don't know about premium channels, but Discovery HD, InHD, InHD2, ESPN, and CSNPHL all seem to be encrypted or something - they don't produce a readable stream. However I have no problem with the HD feeds of the networks, and all the non-HD channels come in fine over the firewire as well. It's all mpeg2 over the firewire. I think the HD channels are the original format from the originator, and the rest is all NTSC-sized mpeg2. I've run into two significant problems so far. First, while myth has no trouble telling the channel to change via firewire, and setting up recordings on different channels works no problem, myth gets extremely upset if you try to change channels while watching live tv, to the point of crashing mythfrontend. I've seen this reported before, and I'm surprised no one's been annoyed with it enough to fix it. As soon as I have a chance to figure out where in the code this is handled, I'm going to try to see if I can figure out a fix, since the WAF is 0 without this. Second, there's one channel that seems to confuse mythfrontend about half the time when it tries to play it. Sometimes it plays back fine, sometimes it locks up or crashes mythfrontend. I don't think mplayer has a problem with streams recorded from this channel (not positive, needs more experimentation). I've seen suggestions for using some perl script or mencoder to normalize the stream as a workaround for this, but haven't tried it yet. Note that the lack of DiscoveryHD, ESPN-HD, etc, is for the Philly area. I've seen reports that in some areas, these come in fine. -Jerry _______________________________________________ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
