Upgraded to 1.01.24, youtube works great as expected (I use only SD content) but the audio goes out after every few minutes while playing some DVD ISO files. FastForward couple seconds and Play seems to work for few minutes before the problem repeats. Plain stupid, will go back to 1.01.17 that worked well.
Actuall I did two things, not sure which one helped solve my problem. I reset the box with a paper clip and moved the drive from USB2 to USB1. That helped. Try it if that works for you too.
