vdr-005/dvb-006 flash-frame bug report

[Guido Fiala <gfiala@s.netic.de>]

Hallo together,

had last weekend the strange effect, that one recording went well, and another
some hours later showed every a few seconds a flash of a frame about half
an image under it's normal position, also there are heavy frame droppes and
a large audio/video latency.

The failure has to be happened during recording with vdr, because it's
reproducible with those file (after 24min it suddenly starts).

There was no system load during recording, the driver modules were not
reinserted between those recordings, just a number of different stations tuned
in. The effect just had affected the recorded file, tv showed no signs of
failures afterwards. (Signal lost, as i tested during the first recording, is
not the reason for that failure)

If i'am not the only one with this problem - i guess there is hiding a bug
somewhere ;-)

How can i track it down?

Another problem i found (probably addressing vdr alone), that parts of the osd
sometimes vanish: sometimes the main menu does'nt display (but still works),
sometimes just the text inside the menu is missing. After reinserting the
modules anything does work again.

Has someone else recognized a time-lag between pressing stop-ff/fr and the
video actually stopping? The time-lag seems to be proportional to the time you
play fast-forward or fast-rewind. (maybe repeated key-events should be dropped
so long plackback-status has not changed)
The same applies for changing the time of some timers via key left/right (at least with
DEBUG_RMEOTE=1 ;-)
