[mythtv] Fwd: [mythtv-commits] Re: Ticket #796: mythtranscode --mpeg2 won't work with ivtv/dbox2 recordings

[Michael Haas]

Hi Geoffry!

I tried and hacked the "memsize", but it didn't work. I still get those
"deadlock detected" error messages.

As you requested, I've uploaded the first four megabytes of the 640x480
recording. I hope you don't mind me contacting you off-list, but I don't
want the curious to use up all my bandwidth :).

Kind regards,
Michael
