VDR recording glitches

[Thomas Jagoditsch <t.ja@gmx.at>]

hi all !

thanx for your replies to the problem.

tried yesterday evening to tune the hd.
turned on 32bit, 16 multisec, unmasqirq (all turned of) - dma was on
by default.

seems to help a little bit, but eliminated the glitches not
completely. but this really could be a pci-bus bottleneck.
sometimes i think i see a synchronisation between glitches and hd-
led, but its hard to proof that.

before sleepfallin *g* i remembered a problem with cd-recording on an
old p120 nt-box some years ago. got underruns always and moved to w95
to make succesfull burns - the reason was that this box got much
memory and virtually all of it was used as cache, a nt-behavior which
could not be turned off.

maybe we´ve got an compareable case here, maybe it would be better to
write every 2,3 seconds but to write big data every 15-20.

wbr.tja...
