[linux-dvb] Re: Replaying SAT.1: Video stays blank - audio is ok

[Ralf Bauer <RBauer@quark.de>]

I checked all drivers beginning from 6.8. up to the latest driver.
I found that the latest driver which is able to replay SAT1, recorded with a
NOVA card is the driver from 13.8.
All newer drivers do not work for me and show the problem stated below.

These are the changes from the change log between the last working driver
and the first non working driver. Unfortunately there are many changes,
including changes in Dpram. Could it be the change in dmxdev.c?

	* driver/L64781.c: typo

2001-08-15 03:28  rjkm
	* driver/L64781.c: new patch by Holger to prevent some EEPROMs of
	being detected as DVB-T demodulator

2001-08-14 13:55  rjkm
	* driver/: Dpram, Root: oops, small bug in YUV output

2001-08-14 02:43  rjkm
	* driver/: Dpram, Makefile, Root, dvb.c, dvb.h, dvb_demodulator.h,
	dvb_filter.h, tuner.c, tuner.h: DVB-T patches from Holger
	
	first steps towards a better firmware crash recovery
	
	auto-detect CS audio DAC

2001-08-14 02:29  rjkm
	* driver/dmxdev.c: hopefully the last fix of the filter reset stuff
	...

I updated yesterday to the latest driver in CVS.
After I did that I saw an old problem again, which was also reported by
Anton Schegg (see his mail below). I hoped I would never see that problem
again.

When I record SAT1 with a DVB-S card everything works fine, when I record it
with a NOVA card, I hear only the audio, but see a black screen. When I
switched back to an older version of the driver, I could replay the SAT1
recording correctly. So the recorded data is correct, but replay does not
work. I also checked with Klaus' xlist.c and the data looks ok for me.

Anton, do you still have this problem?

I'm using VDR-0.93, because I have another strange problem which nobody
reported so far:
When using VDR-0.94, replay of any recording (old and newly recorded) does
not work at all. The screen goes black for about 5 seconds without any audio
and switches back to live video. There are no messages in the log-file, the
VDR processes start and stop normally.

Does anybody have a similar problem?

Ralf.

I had exactly the same problem with the driver from Klaus ftp-server. But I
don't have the problem when I get the driver via CVS from linuxtv.org and
apply Klaus patch.

I'm using driver 2001-08-23 and have no problems replaying recordings from
Sat.1 (or any other channel).
