[linux-dvb] play_iframe not working

[Klaus Schmidinger <Klaus.Schmidinger@cadsoft.de>]

The 'play_iframe()' function apparently hasn't been working since driver
version 2001-06-18, and still doesn't in the latest CVS driver version.

If one replaces play_iframe() in DVB/driver/dvb.c with the version from
2001-06-18, displaying still pictures (e.g. in VDR's edit mode) works fine
again.

Here's a back patch - I assume that the new version is supposed to be
better than the old one, but apparently something must have gone wrong here...
