I used 1.1.17 for some time and had lots of problems. Some days ago I 
switched to 1.1.22. I lost some recordings right away. I disabled
the two defines for simultanious recording/playbayck. After that there 
were no more stability problems. :-)

But: I have recordings that seem to be corrupted in some way. The can be 
viewed without distortions, but sometimes they just get stuck. I need to 
skip over these moments. Generally fast forward/backword does not work 
good with these recordings, like the index had been produced with genindex.

Have you tried to disable the two defines? I had high cpu load with my 
1.1.17 (with defines) but not with 1.1.22 (without defines). I don`t 
know about 1.1.22 with defines.

Could this lead to corrupt files?  Maybe we should try Emeralds 
fidbirq() patch!
Is there any tool that checks the integrity of a stream (headers and 
some CRC)?

By the way: anybody using "streamtype" of mpegtools? I tried several 
versions (also the current one frome Metzler brothers page) and only got 
segfaults :-(

hmm
