As far as I can tell, the Via firewire chipsets are very hit or miss. some people have had luck with them, some (like me) have had nothing but trouble with them. If I was to recommend, I'd say get a Texas Instruments, Lucent, or Agere(sp?) chipset. I have an NEC on the board I ended up getting, which so far has been great, so if you've got one, you should be ok. I've also talked to a couple folks with Sound Blaster Audigy's that have had excellent results using the sound cards firewire, I think they may use TI or Lucent chips on their boards. I found that those who compiled their firewire library's seem to do better than those that used precompiled packages. Though this may be coincidence, so if your distribution has the required library's as packages, try them before compiling your own. But, I did spend some time analyzing how my setup worked and had an idea, and I talked to a couple dev's about it. One suggested I try something before trying my idea. Apparently a few months back this came up on the list and an idea came up.... What he suggested was to set the firewire cable box to use broadcast in mythtv-setup, even if p2p is the only settings that "sticks" when using plugctl. (so get the port and node right, set it to broadcast, 400MB/S). First, if you have any automated scripts to run plugctl to change settings, disable them, we don't want to change the "natural" state of the firewire bus for this experiement. So, shut down the mythbox, unplug the cable box power, and then turn on the mythbox followed by the cable box. This should reset the firewire bus at both ends. I did this last thursday but have been gone all weekend. From the point I did it till I left I never missed a recording, data streamed every time. But I got some missed channel changes. I need to check now to see how it did over the weekend. Give this a try. Let me know if you notice any change in the bahviour of your setup. -- Steve _______________________________________________ mythtv-users mailing list [email protected] http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
