It's been so long since I bumped up to -G 54 for timeshifting I don't remember, but when I tested it the reduction was worth enough to convince me that it was worth staying with. I'd have to run a test with/without to give you actual numbers, which I can do if you'd like. > > q_scale_type=1, satlim=2047, nonsat_mquant=0x40c5602c) > > at quantize_x86.c:309 > > 309 mulps_m2r( *(mmx_t*)&piqf[0], xmm2 ); > > The problem would seem to be in accessing the non intra quant > tables.

Two new runs: lav2yuv t.cut | mpeg2enc.cvs.2003.11.04 -f 8 -V 230 -b 9576 -q 10 -o t.m2v lav2yuv t.cut | mpeg2enc.cvs.2003.11.04 -f 5 -V 230 -b 9576 -q 10 -o t.m2v Both dumped core, with the same gdb backtrace as before. I'm at a loss to explain it so far. And it does not seem to be localized to SVCD, as -f 8 did the same. Yes, it does look like something localized to my system, but I can't pin it down just yet. ------------------------------------------------------- This SF.Net email sponsored by: ApacheCon 2003, 16-19 November in Las Vegas.
