well, I had time to try out your patch. It applied cleanly and using
"750" for the arch seemed to do the right thing. Once installed I gave
it a whirl with mixed results. The frontend worked beautifully.
Watching a recording also yielded really great looking smooth playback
of my 480x480 mpeg4 recordings. I was pretty happy that my old 400mhz
imac could do that (and easily it seems!) However, recordings had
messed up sound. It sounded like HAL from 2001 when he is being shut
down. Slowwww and lowwww. Sounded like a drug trip. However, the sound
did seem to somewhat match the action.
Console showed this message:

Otherwise sound seems to work fine on this system with Mandrake 9.1. I
know that doesn't really make it myth's (or your patch's) fault yet,
because a lot of people seem to have working sound, but still have
trouble getting sound to work with mythtv. However, I'm not trying for
recording and playing at the same time so I don't need duplex, so I was
hoping it would just work. Any ideas?
I thought of manually installing alsa from source since that worked to
get my x86 mandrake 9.1 sound working with mythtv, where the included
alsa didn't work for me. But I don't know the name of the sound card in
this imac, and couldn't really figure it out from the sound cards page
on the alsa website, so i didn't do that.
Finally, here is my modules.conf file:
alias eth0 gmac
probeall usb-interface usb-ohci
alias ieee1394-controller ohci1394
alias sound-slot-0 dmasound_pmac
pretty simple eh? Anyway, if anyone has any advice, or success getting
this going on an imac, I would love to hear about it. In the meantime I
appreciate your work with the patches, I'm a lot closer than I was
before!
best,
Cedar
ps
Mandrake 9.1 seems really snappy on my imac! It rivals the
responsiveness and perceived quickness of my much faster amd system.
However that impression was different during the compile. That took a
really long time.
