TS file format input from DVB receiver gives extremely slow video but DVDs OK

[daved@…]

running "mplayer /dev/dvb/adaptor0/dvr0" after starting "tzap -r channel_name"
results in video output of only 2-3 frames per second, while audio OK. After
30 seconds or so, video becomes normal, but lagging many seconds behind audio
which then has periodic interruptions.

Reproducible on two machines:

• Intel(R) Core(TM)2 Quad CPU Q9400 @ 2.66GHz; openSuSE 11.1
• Intel(R) Core(TM)2 Duo CPU T7300 @ 2.00GHz; openSuSE 11.2

with two different USB DBV receivers.

Mplayer will play DVDs and mpeg files perfectly on both machines.

Running "tzap -o video_file" and subsequently "mplayer video_file" gives perfect
output.

On the second machine, running ubuntu 9.10 from a CD (not installed to disk)
and running the same tzap and mplayer binaries and most libraries (from the
openSuSE filesystem) gave perfect results. The X servers are different:

openSuSE X.Org X Server 1.6.5
ubuntu X.Org X Server 1.6.4

/proc/mtrr same on both systems:

Your system is too SLOW to play this!

(surprising given a DVD can be played)

and later
Too many video packets in the buffer: (104 in 33685480 bytes).
Maybe you are playing a non-interleaved stream/file or the codec failed?
For AVI files, try to force non-interleaved mode with the -ni option.

Another interesting observation: kaffeine can read from the DVD adaptor directly and give perfect audio and video on both machines. But I much prefer mplayer, at least I did until this problem arose when I upgraded my machines.
