1. There is still a bug that some users who are using other file formats are having where certain unidentified files are locking up the service so it won't add any new files. I have still not been able to reproduce this myself. I believe this bug is in the last general release as well.
2. It seems that on the new Ceton Echo that if you are watching something and start navigating the Recorded TV HD menus, the Ceton Echo will simply reboot itself after a few seconds of navigating.
I generally don't install alpha code at the risk of interfering with my Wife's TV viewing.
But, are you saying your alpha version is as stable as a general release?
I am only looking to playback WTV files created using WMC with an InfniTV card.
I guess it depends on what your definition of alpha is. I never put half implemented features into a public release. I also always test on my own setup where any code has changed and hopefully find any side effects of any code changes.
I guess what I'm saying is that I am almost constantly running alpha versions on my setup that my wife uses every day and I always make sure before the next day that things are working properly :) ... It is completely your decision.
