They do both ATSC and QAM. If that's true, then that's a good reason to avoid the air2pc cards. I know that pchdtv is funding some of the MythTV devs to improve various areas, including some that aren't directly related to just the pcHDTV cards. One feature on their list to be done is the ability to save off separate streams from one channel, so for me that means that I could record all 5 different PBS programs at once with one pcHDTV card. I'd much rather have this functionality than saving 2% CPU usage and a little IO. Also, when recording 4 shows at once now with 4 cards my AMD 2600 it is 97% idle, so a couple extra % is not going to make any difference in performance. My guess is that the pcHDTV cards will stay as best supported cards for an extremely long time. They're purely a Linux company, for Linux. They have paid developers to make things better including OSS projects. And since the card is right at the same price as others, I'd much rather support them then another non linux company. --Brandon ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users

Re: [mythtv-users] DViCO FusionHDTV DVB (ATSC/QAM) and MythTV
Check the Linux-DVB mailing list, there are some recent posts by Mac Michaels and Michael Krufky regarding Fusion5 support.I think that the driver for the Fusion5 is in progress now. I think the HD3000 will support QAM. It appears that people have had difficulty making it work, but I haven't tried yet. I'll post a message with my results after I give that a try.

Can someone confirm which card I'll want to buy if I want my HDTV via QAM over cable? I was referring to Linux support in general, not specifically stating the PCHD300 is a safe bet for QAM. I have no idea if it does or does not support QAM as I'm only interested in OTA. Following up on my own question, if I had bothered to look at the dvb- linux list for 10min I would have seen that the FusionHDTV5 is not yet supported in Linux. -- Scott <[EMAIL PROTECTED]> AIM: BlueCame1 ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users

The HD-3000 also does QAM as well as ATSC. (The HD-2000 is no longer being sold.) The Air2PC can send only the requested program stream instead of the full transport stream, reducing the data sent over the PCI bus and somewhat reducing the CPU overhead. They do both ATSC and QAM. I don't know anything about the Fusion HDTV cards, but apparently they also do both ATSC and QAM. So all three cards should work with the right drivers for either ATSC or QAM. I don't know which one works best, which is an important question if you're pulling in an imperfect OTA signal. --PC ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users

[mythtv-users] DViCO FusionHDTV DVB (ATSC/QAM) and MythTV
Some people were having trouble getting the FusionHDTV3 QAM cards working with MythTV. So, here is a short summary of how I got MythTV working with my FusionHDTV3 card. This process should be similar for other DVB cards. I am able to receive both Over-The-Air broadcasts (ATSC broadcasts using 8VSB) and clear channels on my Comcast cable system using QAM256. - Linux OS Install. I used Gentoo AMD64. (Basic OS install & setup.. load standard packages + requirements for MythTV) - Xorg, KDE, MySQL, etc. - Update kernel to 2.6.13rc3-mm1, which includes FusionHDTV and general DVB updates. - Make sure to include modules for Video4Linux, DVB, Conexant 2388x (plus DVB), and lgdt3302 frontend - Rebuild NVidia drivers for new kernel - In Gentoo's /etc/modules.autoload.d/kernel-2.6, I load: cx88-blackbird dvb-core lgdt3302 cx88_dvb - use "dvb-apps" to confirm that card is recognized and functional. Check the docs in the dvb-apps package for details and channel config files. I am using the QAM/Cable channel frequency configs here. - azap -r C79 -c QAM_Channels.conf - this should output lines showing "FE_HAS_LOCK", like the following: status 1f | signal ffa2 | snr | ber | unc | FE_HAS_LOCK - Leave azap running, and in another terminal run "dvbtraffic", it should show information about the PIDs seen in the transport stream on that channel. --- Once you've confirmed that the card is functioning correctly, go on to the MythTV setup. - Install MySQL, set to run on system startup, set root password - Follow mysql setup: http://www.mythtv.org/docs/mythtv- HOWTO-6.html ( Install MySQL, start server, set admin account and define password, input the MythTV schema with mc.sql, set basic access privilegs so MythTV can talk to database) - Setting root password is not covered in the MythTV document, MySQl docs cover this: http://dev.mysql.com/doc/mysql/en/default- privileges.html - Install MythTV. Most Linux distro's will have a recent version available via their package manager. Depending on the build options used to create the available package, it may or may not have all the necessary options (DVB support is needed, XvMC support is useful, etc.). - I used subversion (svn) to grab the latest development snapshot ( see http://cvs.mythtv.org/ ), or grab a tar file of the source for the current stable version from mythtv.org - Use 'configure' to set up mythtv with needed options ( --enable- dvb --enable-xvmc --enable-lirc --enable-proc-opt --enable-opengl- vsync ) - make - make install Run mythtv-setup Basic Setup: - entered mysql user/passwd defined above - Backend setup, ATSC TV Format us-cable frequencies Capture Card Setup: Type: DVB (Should show card 0 as DViCO FusionHDTV 3 Gold-Q -- or similar) Video Sources: Name video source and input zap2it account information. Retrieve Lineups Input Connections: Select Video source defined above. Set "Starting Channel" to a known valid channel you receive. If MythTV starts up and cannot tune a channel, it doesn't react well. Scan for Channels. First, select an ATSC scan, to scan for OTA/8VSB channels (even if you're using QAM / Cable --- (Is this still necessary?)) Then, do a QAM scan, which should result in more channels found. If your cable company is broadcasting the PSIP channel data, the channels should be automatically detected. For channels without PSIP data, you will need to manually edit the channel data (in the mysql database) to enable those channels. ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
