2003-09-14 - Moved the tuner card to "phoenix", my Compaq DL380 server. Now I can use the PIII desktop as a client and (hopefully) run it diskless. I was using the on-board sound on the desktop so I had to use a SoundBlaster Live! card that I had lying around in the server.
2003-09-16 - Turns out sound was more complicated than I thought. Mythtv always records and then plays the recording back; that's how it can do things like pause and rewind "live" tv. So you need to set up the sound card so it is recording the Line input but it must be muted. The biggest hassle was figuring out what the different features of the SoundBlaster Live card were and how they worked.
Here's a dump of the card with a working config:
All of the pictures had strange jagged lines when things moved. It turns out there's an option to "de-interlace" the video on the client side. It crashes on the PII machine but works fine on the PIII.
XVideo and Xinerama don't play nice so it looks as if I can't watch TV on my dual-head machine. That's sort of OK since it doesn't have quite enough CPU either.
2003-09-19 - the wierdest problem so far. Cable channels 2 and channel 14 (WGBH-2 and WGBX-44) didn't have the right audio - they had the BBC instead. I as seriously stumped until I noticed that channel 6 (WFXT-25) was in Spanish. Googling for "Mythtv SAP" did the trick. Turns out there's some really random bttv module option that fixed it:
options bttv audiomux=0x56664e
In debian you add this to /etc/modutils/arch/i386, in other flavors of GNU/Linux I think it's =/etc/modutils/.
