VDR recording glitches

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

hi !

first of all, i want to thank klaus, ralph and all the other guys
which made VDR/DVB possible. i needed only a couple of hours (and
some money *g*) with really null pc-video know-how to set it up and
the whole thing is very promising.

watching sat works flawlessly and the picture is perfect. channels
which _didnt work_ with haupauges windoof-soft (installed with a
clean w98SE only to test the card - found out that i needed a new
lnc) are working too *bg (they seem to have problems with 22k symrate
channels).

recording, too, works (after reading the outstream=0 posts ;-) but
every couple of seconds ive got those block fragments on screen and
on "tape", especially when the picture is quickly changin, like on
mtv, but sometimes on "quiet" scenes too, like "orf-zib2".

the pc is a p200 with 48mb ram, ive purchased a brand new 45gig wd
disk so disk-speed should be no issue. top tells me that memory is
good (not much "free" but big buffers anyway) and cpu utilization is
always under 15%, most of the time around 10%.

for safety i try to shut down all unnecessary daemons but that doesnt
change anything (subjectivly, hard to measure this).

btw. this is the haupauge card, siemens doesnt sell theirs in or to
austria, funny thing (anybody got a CI-card yet ?!?).

questions:
anybody got a good idea ? what could be the bottleneck ?
what systems do you use ?
in the long run, i would like to equip the pc with a second card,
should i assemble a bigger VDR-pc ? will it help ?

thanx for any input in advance.

thoughts on VDR/DVB evolution:
- teletext would be a nice thing, especially in combination with
"point & click timer-programming"
- integrated dvd/cd/mp3-playback (screen-output with random jpgs for
cd/mp3) would make VDR a real multimedia-settop
- vbox-integration is on my mind too, in the moment this is done by
an old notebook - maybe some sort of easy "user-defined menus" for tv
can accomplish such whishes
- visually remote control of the other hifi-video components could be
comfortable (i dig thru LIRC docs at the moment ;-), somebody could
do nice things (back up VDR to a VCR, switch inputs on the
receiver/amp ...)

wbr.tja...

ps: i´m not that big programmer-guy anymore, especially not on low-
level linux, but if there is something to test, write dox etc. i
would be happy to contribute.
