Hallo, this week I experimented a lot with different settings. probably I need to add that I do not know anything about PCI busses and brooktree chips.
- When changing the latency timings I observed the the original delay (32) was a good compromise between the artifacts and inserted/deleted frames. - I used a VHS tape as a source and recorded the same sequence (up to a random offset) with different settings. It seems that the artifacts depend on the picture contents (or sound contents?) of what is recorded. The lines appeared always on the same frames at identical positions. - In my old OS setting (SuSE 7.2), I never observed these artifacts. Recently, I upgraded to SuSE 9.0. - Downgrading mjepegtools to 1.6.1 did not help. - Recording under W98 on the same machine (VirtualDUB/Morgan MJPEG) worked fine. These effects seem to indicate that the problem is related to driver/kernel or such. Is there anything what I can try else (besides capturing under W98)? Thank you.
