Hi,
the 1st line of the tv picture is constantly dashed here, e.g.
- - - -- - -- -- - - -- -- ----------------------
This is a cosmetic problem but nevertheless annoying !
I think this problem existed since the early days of bttv.
Do others see this artefact, too?
Any clueful hints on causes for this?
Regards, Gunther
P.S.
Further data/Kind-of-Workaround:
When switching to "grabdisplay" in the default size 384x288
the line is fine (and the pictures increases sligtly in size,
both horizontal and vertical) !
This does not help as soon as vsize>288, so this could be
a subtle scaling problem in the BTTV-Risc code or similar?
Side note: With "grabdisplay" unfortunately the last line is wrong:-(
| ------------------- |
The artefacts combination depends on the tv channel selected:
RTL (CH60) in the only channel without artefacts, here!
