powerdvd 13 seems pretty buggy to me.
h264 with lossless audio in m2ts container - copied from bluray disc [mine, genuine] has stutter issues software/hardware decode [truetheater effects on/off] - hardware has it reduced to a single frameskip every so often as oppsed to software with starts fine and a minute later is jerking.
freeze on exit. pretty common. it happens after configuring powerdvd's settings. i make a lot of changes. the program uses maximum cpu under a single thread constantly so you can't run another powerdvd session [powerdvd is already running] you have to force close it. fortunately settings are saved.
i remove all file associations from powerdvd, yet they remain under windows explorer. not good.
