I just tried with that patch, it gives me about 100kBaud TTX, but no EPG data. I've already set ivtv_std=2, at least I hope so (using autoload on startup). The raw size it reports is 1444, so it should be okay.
These are the messages after starting a vbi capture (including the patch): May 23 07:31:02 david saa7115: status: 0x91 May 23 07:31:02 david ivtv: Allocate DMA stream 2 using 165 12635 byte buffers 2097152 kbytes total May 23 07:31:02 david saa7115: decoder disable output May 23 07:31:03 david saa7115: decoder enable output May 23 07:31:03 david ivtv: Setup VBI API header 0x0000bd05 pkts 1 buffs 4 ln 36 sz 1444 May 23 07:31:03 david ivtv: Setup VBI start 0x0018ea04 frames 4 fpi 1 lines 0x000000f1 May 23 07:31:03 david saa7115: decoder disable output May 23 07:31:03 david saa7115: decoder enable output May 23 07:31:04 david ivtv: VBI Offset mismatch by 128 bytes now at 0x0018ea90 index 1 frame 4 I'm willing to do more tests, but will be away for a week now. I'll check the mailing list when I'm back.
