[mythtv-users] Confused about IEE1394 when upgrading

Hi,
The newer kernels have reworked firewire. In the past I've had to put
backwards-compatible stuff in mythtv to get firewire working. However,
Fedora 12 recorded off firewire "out of the box", so I suspect that much
of the wiki, etc., about firewire is now out of date and misleading.
System:
Motorola DCT6200 connected by firewire (channel changing and record) and
svideo (for channels that aren't firewire-enabled).
Fedora 12 kernel 2.6.31.9-174.fc12.x86_64
atrpms for mythtv packages, etc.
Dual-core Athlon 64 5000
PVT250 for SVIDEO and analog cable channels
A QAM256 tuner for non-encrypted (works fine).
HD PVR (still in box awaiting successful upgrade). Will augment or
replace svideo recording from the cable STB.
After the upgrade, the firewire tuner changed channels and recorded
fine. In fact, it is far more reliable. (On the old system, firewire
channel changing was reliable but recording was hit-and-miss; each
recording would either work or would fail immediately and get the
firewire modules into a messed-up state.)
In order to use SVIDEO and/or HD PVR, I'll need to change channels. On
the old system, I use 6200ch for that purpose, but it and the other
tools like plugreport all look for /lib/raw1394, which doesn't exist.
Clearly *mythbackend* doesn't it to change channels, but I see no way to
configure things to use anything but an external changer for
non-firewire tuners.
Questions
1. Do I need 6200ch (or some other external program) to change channels
when using the HD PVR to record? (Clearly mythbackend "knows" how to
change the channel -- it does so when recording from firewire. I see
nothing other than "external channel changer" for use with STB+HD-PVR.)
2. Is there a "more modern" program or better program than 6200ch?
3. If not, what do I need to get /lib/raw1394?
Thanks for any insight,
Len
